These lessons, with videos, examples and solutions, help Grade 7 students learn how to compute unit rates associated with ratios of fractions, including ratios of lengths, areas and other quantities measured in like or different units.
For example, if a person walks 1/2 mile in each 1/4 hour, compute the unit rate as the complex fraction 1/2/1/4 miles per hour, equivalently 2 miles per hour.
Common Core: 7.RP.1
The following diagram shows how unit rates can be used to solve problems. Scroll down the page for more examples and solutions on how to use unit rates.
