Understanding Ratios and Proportions
A ratio compares two quantities, while a proportion is an equation stating that two ratios are equal. In the form A:B = C:D, the product of the means (B × C) is equal to the product of the extremes (A × D).
Solve for missing values in proportions (A:B = C:X).
Leave one field blank to solve for it.
