Ratio and Proportion Review

A ratio is a comparison of two quantities that shows the relative size of one quantity to another, often expressed as 'a:b'.

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

To find an equivalent ratio, you can multiply or divide both terms of the ratio by the same non-zero number.

The ratio of guards to forwards is 8:5.

Shanni's ribbon is 8 times longer than Mel's ribbon.
