Understanding Equivalent Ratios

The video tutorial from Moomoomath explains equivalent ratios, which show the same comparison between two values and can be used to find missing values. The tutorial provides three examples: calculating the distance a car travels in a given time, determining the time a runner takes to cover a certain distance, and finding the number of males in a class based on the number of females. Each example uses a box method to solve the problem, emphasizing the importance of maintaining the ratio by performing the same operation on both sides.

What is the primary purpose of equivalent ratios?

• To determine the average of a set of numbers

• To find the sum of two numbers

• To compare two different values

• To solve algebraic equations
