Task# Equivalent Ratios and Unit Rates

Illustrative MathematicsVaries

This task should come after students have done extensive work with representing equivalent ratios and understand that for any ratio a:b, the ratio sa:sb is equivalent to it for any s > 0. The purpose of this task is to make explicit the fact that equivalent ratios have the same unit rate. A solid understanding of this fact will allow students to solve problems involving equivalent ratios in a very efficient manner.
