Fraction Calculator
Add, subtract, multiply and divide fractions — with the steps.
Fraction Calculator adds, subtracts, multiplies and divides fractions and mixed numbers, simplifies the result to lowest terms, and shows every step: common denominator, the operation, and the reduction. It also converts fractions to decimals and decimals back to exact fractions, all worked out in the page.

Questions about Fraction Calculator
Does it show how the answer was reached?
Yes, that is the point. Every step is written out — the least common denominator, the converted numerators, the operation, and the greatest common divisor used to reduce the result.
Can it handle mixed numbers?
Yes. Enter them as
2 3/4 and the answer is offered both as an improper fraction and as a mixed number.How does decimal to fraction work?
Terminating decimals convert exactly. Repeating decimals are detected and converted using the standard algebraic method, so 0.333... becomes 1/3 rather than 333/1000.
Can it take three or more fractions at once?
No — it works on two operands at a time. Chain them by feeding the answer back in as the first fraction, which is also how the working would be laid out on paper. Long chains are easier to follow that way than as one line.
Is it any use for showing working in homework?
That is what the step list is for. The least common denominator, the converted numerators, the operation and the reduction are all written out, so you can copy the reasoning rather than only the result. Whether that is allowed is between you and your teacher.
Is Fraction Calculator really free, with no limits?
Yes. There is no account, no daily cap, no file-size tier and no watermark, because there is no server cost to recover. The site is funded by clearly disclosed partner recommendations on the Partners page, never by metering the tools.
Are my files or text uploaded when I use Fraction Calculator?
No. Everything is processed by JavaScript running in your browser, on your device. You can verify it: open your browser's developer tools, switch to the Network tab, and use the tool. You will see no request carrying your data — because there is nowhere for it to go.
