➗ Fraction Calculator
Enter two fractions, choose an operation, and get the simplified result, its mixed-number form, and the decimal value instantly. Toolio's Fraction Calculator supports whole numbers and even decimal numerators or denominators, and runs entirely in your browser — free, private, and offline-capable.
- Leave the whole-number box empty for a plain fraction like 3/4.
- Numerators and denominators may be decimals — 2.5/4 works too.
- Everything runs in your browser. Nothing is uploaded.
Private by design. This tool runs entirely in your browser — nothing you enter is uploaded or stored, and it works offline.
About
This calculator handles the four core fraction operations — addition, subtraction, multiplication and division — and always reduces the answer to lowest terms using the greatest common divisor. It shows three representations at once: the simplified fraction, the mixed number (whole part plus remainder), and the decimal/percent equivalent, plus a one-line breakdown of the calculation so you can check the working. Because it runs client-side, nothing you type is uploaded or stored on a server.
How to use
- Type the numerator and denominator of the first fraction (add a whole number if you have a mixed number).
- Pick the operation: + , − , × or ÷.
- Enter the second fraction. The result updates instantly as you type.
- Read the simplified fraction, mixed number, and decimal — or click 'Copy result'.
FAQ
- Does it simplify the answer automatically?
- Yes. Every result is reduced to lowest terms and also shown as a mixed number and a decimal.
- Can I use decimals in the numerator or denominator?
- Yes — values like 2.5/4 are handled by scaling to whole numbers internally before calculating.
- Is it free and private?
- Completely free, no login, and all math runs in your browser — nothing is uploaded.
