Learning Objective

I can calculate unit rates from ratios and proportional relationships.

Rates compare and show the relationship between quantities with different units.

A unit rate is a rate with a denominator of one; it shows per one unit.

To find a unit rate, divide the numerator and denominator of the rate by the denominator to get a denominator of one.
