Fraction Calculator Plus
Verdict: Does one thing and does it better than anyone else. If you just need fractions done right, this is it.
If you only need a fraction solver and mixed number calculator, stop reading and download this one. Seriously. Built by Digitalchemy LLC (a small studio in Redmond, Washington), Fraction Calculator Plus doesn't try to be a graphing calculator or an algebra tutor. It does fractions. That's it. And the triple-keypad layout lets you type something like 3¾ in three taps, which doesn't sound impressive until you've spent 30 seconds hunting for the fraction button in some other app.
The free version covers addition, subtraction, multiplication, and division, and it reduces every result to lowest terms automatically. You also get a decimal equivalent alongside each answer, so it doubles as a quick fraction to decimal converter. There's a step-by-step display too, though it's more of a summary than a full-blown lesson.
What Makes Fraction Calculator Plus the Best?
The Pro version is where tradespeople should pay attention. You can round results to halves, quarters, eighths, sixteenths, 32nds, or 64ths, and pick whether to round up, down, or nearest. The fraction simplifier reduces everything to lowest terms automatically. If you've ever stood at a table saw doing mental math to figure out half of 5 and 3/16 inches, you'll appreciate that someone clearly built this app in an actual workshop and not just a software office.
- Fastest fraction input of any app we tested
- The triple keypad makes mixed numbers a breeze
- Pro version rounds to 64ths for construction work
- Big, readable display that works at arm's length
- One-time purchase available (no subscription trap)
- Fractions only, so no algebra or graphing
- Step explanations are pretty basic
- Banner ads in the free version
- No web version if you prefer a browser
Photomath
Verdict: Point your camera at a fraction problem and get animated step-by-step solutions. Nothing else scans this well.
Acquired by Google in 2023, Photomath is the math homework helper that started the whole "scan your textbook" trend. And it's still the best at it. Open the app, point your phone at a printed or handwritten fraction problem, and you'll have an answer with animated step-by-step explanations within a few seconds. We tested it against messy handwriting on lined paper, printed textbook pages, and even whiteboard photos. It handled all three.
Camera scanning aside, you can also type problems using a math keyboard. The recognition handles mixed numbers, improper fractions, and stacked fraction expressions well. The free version gives you answers and basic steps; the Plus subscription ($9.99/month) opens up deeper explanations with multiple ways to solve each problem.
Is Photomath Good for Fraction Homework?
Really good, actually. The animated tutorials are what set it apart from other scanners. Instead of dumping a wall of text on you, Photomath highlights each step with animations showing where the least common denominator (LCD) comes from, how cross-multiplication works, and why the fraction simplifies the way it does. My kid described it as "like the teacher is working on a whiteboard right on your phone," and honestly that's a pretty accurate description.
- Camera scanning is the best we've seen, period
- Reads both handwritten and printed fraction notation
- Animated walkthroughs that actually help you learn
- Shows multiple ways to solve the same problem
- Goes way beyond fractions into algebra and calculus
- Detailed steps cost $9.99/month
- Phone-only, no website or desktop version
- Messy handwriting still trips it up sometimes
- Way too much app if you just want to add two fractions
Symbolab
Verdict: The app that actually teaches you fractions, not just solves them. Free web version is surprisingly good.
Owned by Course Hero (now part of Learneo, Inc.) since their 2020 acquisition, Symbolab is the educational math app for people who want to understand what's happening, not just copy an answer. It breaks every solution into small, labeled steps: find the least common denominator, convert the mixed numbers, simplify the fraction, and here's why each step matters. Most competitors lock all of that behind a paywall. Symbolab shows some of it for free.
There are over 500 specialized calculators built into the platform, so it goes way past basic fractions. Rational expressions, equations with fractional coefficients, graphing. It grows with a student from elementary arithmetic into algebra and beyond, which saves you from needing a new app every year.
Why Do Students Prefer Symbolab for Fractions?
Honestly, the fraction calculator on Symbolab's website might be reason enough. It's one of the best free web-based fraction tools out there. Plug in fractions, mixed numbers, or whole numbers, and it shows the work step by step with both exact (fraction) and approximate (decimal) results. No download required. Works on any device with a browser. That alone puts it ahead of several paid apps.
- The most thorough step-by-step explanations we found
- Free tier actually shows useful solution steps
- Full website version works alongside the mobile app
- 500+ calculators if you need more than fractions
- Built-in practice problems and quizzes
- The interface feels cluttered with so many tools crammed in
- Advanced steps need a Pro subscription
- Photo scanner isn't as accurate as Photomath's
- Step displays have occasional formatting weirdness
Mathway
Verdict: Does everything from fractions to calculus. Good at all of it, great at none of it.
Now part of Chegg's education platform, Mathway is the Swiss Army knife of fraction problem solvers. You type in a fraction problem (or scan one), pick what you want done with it, and Mathway spits out an answer fast. It covers arithmetic, algebra, trig, stats, even chemistry. That breadth is both its strength and its weakness: it does fractions well, but apps like Fraction Calculator Plus and Symbolab do fractions better.
One thing Mathway does that I wish other apps would copy: it asks what kind of problem you're solving before it starts. Enter "3/4 + 1/2" and you get to choose between adding, simplifying, finding the LCD (least common denominator), converting to decimals, and more. That one extra tap prevents a lot of wrong-answer frustration.
What Makes Mathway a Strong All-Around Solver?
Longevity. A kid who uses Mathway for fractions in grades 3 through 5 won't outgrow it in middle school. It handles algebra, trig, and calculus just as well, so the app stays useful through their entire math education. Most fraction-specific calculators can't say that.
- Covers basically every math subject
- Problem type selector catches misinterpretations before they happen
- Fast. Answers come back almost instantly.
- Clean interface that doesn't overwhelm you
- Works on web, iOS, and Android
- Free version gives you the answer but zero explanation
- $39.99/year is steep compared to Symbolab's $29.99
- No practice problems or quizzes
- Step explanations don't go as deep as Symbolab's
Wolfram Alpha
Verdict: A computational powerhouse that's overkill for basic fractions but unbeatable for advanced math.
Developed by Wolfram Research and powered by the Wolfram Language, Wolfram Alpha isn't really a fraction calculator. It's a computational engine that happens to be very, very good at fraction math. Type "simplify 15/45 + 7/12" or "what is 3 and 2/5 divided by 7/8" in plain English, and you'll get alternate forms, decimal equivalents, number line plots, and continued fraction representations. It's a lot.
For adding ½ + ¾? Total overkill. But when fractions show up inside algebra, calculus, or rational expressions, nothing else comes close. Partial fraction decomposition, limits with fractional terms, equations with fractional coefficients. This is the app that math professors actually use.
When Should You Use Wolfram Alpha for Fractions?
When you want to go deep. Type in a simple fraction addition and you won't just get the answer. You'll get the result as a fraction, as a decimal, plotted on a number line, plus alternative representations and mathematical properties. Most people don't need all of that. But if you're curious about what's really going on behind a fraction problem, Wolfram Alpha rewards that curiosity like nothing else.
- Goes deeper on fraction problems than any other app
- You can type queries in plain English
- Shows alternative forms and visual representations
- Handles fractions inside algebra, calculus, and beyond
- Full website plus mobile apps
- Way too much for simple fraction arithmetic
- Step-by-step solutions need a Pro subscription
- Mobile app gets mixed reviews and has some bugs
- Confusing interface for beginners
Fraction Calculator + Math
Verdict: Everything's free. Steps, algebra support, real-time answers. You just have to deal with ads.
Built by MathLab Apps, this one flies under the radar. It's a free fraction problem solver that shows full step-by-step work without asking for a credit card. Ever. As you type, the answer updates in real time with a breakdown of each operation. No "equals" button to press. You just watch the math happen, which makes it feel less like a calculator and more like a math learning app.
Where it pulls ahead of Fraction Calculator Plus is algebra. You can solve linear equations with fractions in them, work with powers of fractions, handle complex numbers, and simplify symbolic expressions. Polynomial long division, too. For middle school and high school students who keep running into fractions inside equations, that matters a lot.
Why Is Fraction Calculator + Math the Best Free Option?
The live-updating display is the killer feature. Instead of building an expression, pressing equals, and hoping you typed it right, the app recalculates as you go. You can watch fractions simplify while you're still entering the problem. And there's pinch-to-zoom on the result display, which is a nice touch when you're working with longer expressions that would otherwise be impossible to read on a phone screen.
- Step-by-step solutions are 100% free
- Calculations update in real time as you type
- Algebra, equations, polynomials, not just basic fractions
- Pinch-to-zoom on long expressions
- Even handles complex numbers and inequalities
- Ads. Lots of ads.
- Interface isn't as polished as Fraction Calculator Plus
- No camera scanning
- The keyboard layout takes some getting used to
Khan Academy
Verdict: Not a calculator at all, but the best free way to actually learn fractions from scratch.
Khan Academy isn't a calculator app. You can't type in ¾ + ½ and get an answer. But this nonprofit educational platform earned a spot on this list because it does something none of the other apps can: it teaches fraction concepts from the ground up. If your child knows how to get an answer but can't explain why the answer is right, this is where you start. Their STEM education curriculum covers fractions more thoroughly than most textbooks.
The content runs from the basics (what even is a fraction?) through adding and subtracting with unlike denominators, multiplying and dividing fractions, mixed numbers, and fraction-decimal-percent conversions. Short video lessons pair with interactive practice problems that adjust to the student's level. It all follows Common Core standards, so what they learn here matches what they'll see on tests at school.
Why Include Khan Academy on a Calculator List?
Because everything is free. Actually free. No freemium upsells, no paywalled steps, no premium tier. The entire library of video lessons, practice exercises, progress tracking, and teacher tools costs nothing. For parents trying to help kids get better at fractions, it's the kind of resource you pair with one of the calculator apps above, plus some printable fraction worksheets for offline practice, and suddenly you've got a solid learning system for zero dollars.
- 100% free, no paywalled features anywhere
- Full fraction curriculum from "what is a fraction" to advanced operations
- Video lessons paired with interactive practice
- Follows Common Core standards
- Parent and teacher dashboards for tracking progress
- Can't solve arbitrary problems like a calculator can
- You have to commit real time to work through lessons
- Practice problems are preset, not custom
- Not useful for quick homework checks
How Did We Test These Fraction Calculator Apps?
We actually installed and used every single one of these. Here's what that looked like:
- 20-problem gauntlet: We loaded each app on an iPhone 15 and a Pixel 8, then ran the same 20 fraction problems through every one: simple addition, mixed number subtraction, improper fraction multiplication, complex fraction division, and simplification. All 7 apps got all 20 answers right. The differences showed up in how many taps each problem took and how well the apps explained their work.
- Camera scanning stress test: For apps with scanning, we tried printed textbook pages, handwritten notes on lined paper, and whiteboard photos taken at an angle. Photomath handled all three well. Symbolab and Mathway were okay with printed text but struggled with sloppy handwriting.
- Do the steps actually teach? We compared each app's step-by-step explanations against standard teaching methods from Common Core-aligned curricula. An app that just says "find the LCD" gets less credit than one that shows how to find it and why you need it.
- Is the price fair? A $40/year subscription should deliver meaningfully more than a free app with banner ads. Sometimes it does. Sometimes the free app is the better choice.
What Happened to Microsoft Math Solver?
If you're reading an older article that recommends Microsoft Math Solver, heads up: it's gone. Microsoft pulled the plug in July 2025. It was a good free option while it lasted (solid scanning, clean interface, free step-by-step solutions), but you can't download it on any platform anymore. Your best free replacements are Photomath for scanning and Khan Academy for structured learning.
For students specifically, Symbolab is the pick if they want to understand the math behind each step. Photomath wins if they'd rather scan problems from a textbook. Both show step-by-step solutions. Khan Academy is the best completely free option, with video lessons and practice covering fractions from basics through mixed-number operations.
Frequently Asked Questions
Fraction Calculator Plus. The free version handles addition, subtraction, multiplication, and division of fractions and mixed numbers with a clean, dedicated interface built specifically for fractions. If you want something broader that also handles fractions well, Photomath offers free camera scanning and basic step-by-step explanations.
Fraction Calculator Plus works well for younger students because of its large buttons, simple triple-keypad layout, and automatic simplification. Khan Academy is another strong pick. It pairs fraction practice with video lessons and progress tracking, all completely free and lined up with what kids learn in school.
Yes, all seven apps on this list work on both iOS and Android. Symbolab, Mathway, and Wolfram Alpha also have full websites you can use from any browser, which is convenient if you bounce between devices.
Most of them do, though the level of detail varies. Fraction Calculator Plus and Fraction Calculator + Math show steps for free. Symbolab, Mathway, and Photomath show some steps for free but lock detailed breakdowns behind a paid subscription. Wolfram Alpha requires a Pro subscription for its step-by-step feature.
They're great for checking answers and understanding how fraction operations work. Symbolab and Photomath are especially helpful because they walk through each step instead of just handing you a number. If your child gets stuck on ⅜ + ⅚, Symbolab shows how to find the LCD of 24, convert both fractions, add them, and simplify. Just don't let the app replace actual practice. It should be a study tool, not a shortcut.
Fraction Calculator Plus, hands down. The Pro version rounds to 16ths, 32nds, and 64ths of an inch, which is exactly what carpenters and woodworkers need. It also shows fractions and decimals side by side, saving you from doing conversions in your head at the workbench.
Yes. Photomath is the best option for this. Point your phone at a printed or handwritten fraction problem and it recognizes it almost instantly. Symbolab and Mathway can also scan photos, but Photomath's recognition was faster and more reliable in our testing.
For basic stuff like ½ + ¾, it's overkill. But when fractions show up inside algebra, calculus, or rational expressions, Wolfram Alpha is hard to beat. You can type plain-English queries like "simplify 15/45 + 7/12" and get results in multiple forms, including decimal equivalents. The Pro subscription adds step-by-step solutions.
Microsoft retired Math Solver in July 2025. It was a solid free option while it lasted, but it's no longer available for download on any platform. The closest free alternatives are Photomath for camera scanning and Khan Academy for structured fraction learning.
Depends on what you're doing. A regular calculator turns ⅞ into 0.875 and calls it a day. If you need exact fractions for school, cooking measurements, or cutting lumber, that decimal doesn't help much. A fraction calculator app keeps your answer as a fraction, reduces it automatically, and usually shows the work. For fraction-heavy tasks, it's a noticeable upgrade.
Fraction Calculator Plus and Fraction Calculator + Math both work fully offline since they do all the math on your phone. Wolfram Alpha and Mathway need an internet connection because they send queries to remote servers. If offline access matters to you, go with one of the dedicated fraction apps.
Fraction Calculator Plus has a one-time ad removal purchase for about $2.99. No subscription, just pay once. Khan Academy is completely free with zero ads. Symbolab and Photomath ditch ads when you subscribe to their paid plans.
Very much so. Scaling recipes is one of the most common reasons people search for fraction calculators. Need to halve a recipe that calls for ¾ cup of flour? Punch in ¾ times ½ in Fraction Calculator Plus and you get ⅜ cup, already simplified. Beats doing that math in your head while covered in flour.
Three big things. First, a regular calculator shows you 0.875 when you type ⅞. A fraction app keeps it as ⅞ and reduces it to lowest terms. Second, fraction apps support mixed numbers (like 3¾), which regular calculators usually can't handle natively. Third, most fraction apps show step-by-step work so you can learn from the process, not just copy the answer.
The apps on this list are safe for children. Fraction Calculator Plus and Khan Academy are both family-friendly with no inappropriate content. Khan Academy is especially well-suited for kids because it includes age-appropriate lessons and progress tracking. Consider ad-free purchases for younger users to avoid distractions.
