Fraction calculator

Add, subtract, multiply, or divide two fractions and get the simplified result and decimal.

Accepts fractions like 3/4, integers like 2, and decimals like 1.25.

Computed in this browser. Nothing is sent anywhere.

Exact integer arithmetic up to 10²⁴. Decimals must terminate — recurring input like 0.(3) is not accepted; enter 1/3 instead.

How to use

  1. Enter two values — fractions, integers, or decimals.
  2. Pick the operation.
  3. Read the simplified fraction and its decimal.

What it supports

Exact integer arithmetic up to 10²⁴. Recurring decimals are rejected as input — write 1/3, not 0.333.
