How to Use the Fraction Calculator

Enter two fractions (or mixed numbers) and select the operation — add, subtract, multiply, or divide — and the calculator shows the result, automatically simplified to lowest terms and, if applicable, converted to a mixed number.

The Fraction Calculator handles all four basic operations, including simplification — here's what to enter.

Entering fractions and mixed numbers

Enter each fraction as a numerator and denominator, or as a mixed number (a whole number plus a fraction) if the tool supports that format directly — the calculator handles the conversion and calculation regardless of which format the inputs use.

Choosing an operation and reading the result

Select addition, subtraction, multiplication, or division, and the calculator applies the correct method for that specific operation (common denominators for addition/subtraction, straightforward multiplication of numerators and denominators for multiplication, and reciprocal multiplication for division), returning a fully simplified result.

Frequently asked questions

Does the calculator show work for how it reached the answer?

Check whether the specific tool displays intermediate steps — some fraction calculators show the common denominator or simplification steps explicitly, which is useful for checking understanding, not just getting the final answer.

Can I use this calculator for more than two fractions at once?

For more than two fractions, performing the calculation in steps (combining two at a time, then combining that result with the next fraction) applies the same rules sequentially to reach a final combined answer.
