What is this tool?
Ratios compare quantities; proportions equate two ratios. Use this tool to reduce a ratio to lowest terms, scale it so one side matches a target, or leave one term blank in a proportion to solve for the missing value.
How to use it

- Scale: set a target for side A or B using the same A:B above.
- Proportion: fill three of X,Y,Z,W and leave one blank to solve.
