Understanding Unit Rates

This video tutorial from Mathcation explains how to solve unit rate problems. It begins with an introduction to unit rates, followed by three practice problems: calculating rainfall per hour, determining the cost per can of soda, and finding the price per candy bar. Each problem is solved step-by-step, emphasizing the importance of having a '1' in the denominator to identify a unit rate. The video concludes with additional resources for further practice.

What is the first step in solving a unit rate problem?

• Subtract the denominator from the numerator

• Multiply the numerator and denominator

• Write the ratio as a fraction

• Divide the numerator by the denominator
