What is the unit rate?

Back

The unit rate is a comparison of two different quantities when they are combined together. It is often expressed as a quantity per one unit, such as miles per hour.

Front

How do you find the unit rate from a ratio?

Back

To find the unit rate from a ratio, divide both quantities by the same number to simplify it to a ratio of 1. For example, if the ratio is 60 miles in 2 hours, the unit rate is 30 miles per hour.
