Unit Rate Problem Solving Techniques

The video tutorial from MooMooMath explains how to calculate unit rates using proportions. It begins with an introduction to unit rates and outlines the steps to solve unit rate problems, including setting up a proportion, cross-multiplying, and solving for the unknown variable. The tutorial provides several examples, such as calculating the cost of one orange, the price per pound of pumpkin seeds, the cost of a single shirt, and the distance a car travels in one hour. Each example demonstrates the process of setting up a proportion and solving for the unit rate. The video concludes with encouragement to practice solving unit rate problems.
