About the Fraction Calculator
This fraction calculator performs all four arithmetic operations on two fractions and automatically reduces the result to its simplest form.
Along with the simplified improper fraction, it shows a mixed number and decimal value so you can use the answer in the format your problem requires.
The calculation uses exact integer arithmetic for the fraction itself, avoiding the rounding errors that can appear when fractions are converted to decimals too early.

Frequently asked questions
- How are fractions simplified?
