Equivalent ratios and ratio tables

A ratio is a comparison of two quantities that shows the relative size of one quantity to another.

Two ratios are equivalent if they represent the same relationship between quantities, meaning they can be simplified to the same fraction.

To express a ratio as a fraction, write the first quantity as the numerator and the second quantity as the denominator.

A ratio table is a tool used to organize pairs of equivalent ratios in a structured format.
