Exploring L3 Equivalent Ratios

This video tutorial introduces the use of tape diagrams to find equivalent ratios. It provides examples involving Mason and Laney's running laps, Josie's test results, and a bag of mixed nuts. The tutorial emphasizes the importance of setting up tape diagrams based on given ratios and using division to find values in each box. It aims to help students understand and apply tape diagrams to solve ratio problems effectively.

What is the purpose of using tape diagrams in mathematics?

• To calculate derivatives

• To solve algebraic equations

• To graph functions

• To visualize and solve ratio problems
