Both terms must be positive whole numbers. The simplified ratio preserves the same proportion.

Results are rounded for display; calculations use unrounded values. Read our calculation methodology.

A simplified ratio divides both terms by their greatest common divisor. The decimal shows how large the first term is relative to the second.

Reduce a ratio to its smallest whole-number terms for recipes, scale drawings or comparisons.

Can I use decimals?

Convert both values to equivalent whole numbers first. This calculator accepts positive integers so the simplified form is exact.

Does 3:4 mean 75%?

The first term is 75% of the second. The two terms together are split into seven total parts, so their shares of the whole are different.
