Fraction Calculator

How this calculator works

The fractions use common-denominator or product rules, then divide numerator and denominator by their greatest common divisor.

Change one assumption at a time to see which inputs have the greatest effect on the estimate.

Worked example

One half plus one third simplifies to five sixths.

Limitations

Denominators cannot be zero; very large integer products are outside the supported range.
