Fraction Calculator — free online tool
Fractions are easy to get wrong on paper, and it's tense when you're helping a kid with homework or doubling a recipe. We added a free tool that does the math for you — Fraction Calculator — right in your browser.
What it does
It adds, subtracts, multiplies and divides fractions, and gives you the result already simplified. So instead of finding a common denominator and reducing by hand, you just type the two fractions, pick the operation, and read the clean answer.
Nothing leaves your device
The whole thing runs inside your browser. Your numbers aren't uploaded anywhere, nothing is saved, and there's no account to make. Close the tab and there's no trace left behind.
How to use it
- Open the Fraction Calculator and type in your two fractions.
- Choose what you want to do: add, subtract, multiply or divide.
- Read the simplified result, and copy it where you need it.
It's free with no limit. There are more small tools on the Apps page.
