Ratio Calculator
Simplify ratios, convert ratio parts to percentages, compare decimal form, and split a total by a two-part or multi-part ratio.
Simplify, scale, and split ratios
The main English ratio calculator intent is practical: reduce a ratio to lowest terms, understand each part as a share of the whole, and optionally split a total by those parts.
A ratio compares parts in order. Dividing all parts by a common factor keeps the same relationship.
- Enter two or more non-negative ratio parts.
- Add more parts for recipes, budgets, mixtures, or team shares.
- Enter a total to split it proportionally across the ratio parts.
