Using Equivalent Ratios to Solve Rate Problems

The video tutorial explains how to use equivalent ratios to solve problems, using Melanie's reading speed as an example. It demonstrates setting up original ratios, using a double number line, and calculating how many pages Melanie can read in different time frames, such as 50 minutes and two hours. The tutorial emphasizes the importance of labeling ratios correctly and offers strategies for solving problems step by step.
