Ratio Calculator

Enter two ratio terms. The calculator reduces decimal values without rounding them to arbitrary millionths, shows quotient and percentage context, scales the ratio, and can divide a total into proportional shares.

Ratio A

Ratio B

Scale multiplier

Optional total to split

Quick example

Decimal terms are converted to exact rational values before reduction, rather than being rounded to a fixed number of decimal places.

—Simplified ratio

—Scaled ratio

—A ÷ B

—B ÷ A

—A as % of B

Split total — A share—

Split total — B share—

Combined ratio parts—

A:B

Formula and interpretation

Reduce both ratio terms by their greatest common divisor.

Ratios compare relative quantities; keep units compatible before simplifying.
