About the Ratio Calculator
Four ways to work with ratios, all with full working shown.
What it is
The Ratio Calculator handles the four most common ratio and proportion tasks: simplifying a ratio to lowest terms, solving a missing value in a proportion via cross multiplication, scaling a ratio by a factor, and splitting a total quantity proportionally. Ratios and proportions are closely related to fractions โ every mode shows the arithmetic behind the answer.

Solve proportion
Cross-multiplication solving for any missing term in A:B = C:D.
Scale
Multiply a ratio by a scale factor to get an equivalent ratio.
