Exploring Percent Proportions and Their Applications

This video tutorial explains the percent proportion method, a technique for solving problems involving percents. It covers setting up proportions with two fractions, where one fraction represents the percent and the other represents the part and whole. The video includes examples of finding unknown values such as the percent, part, and whole, and demonstrates solving a word problem using this method. Practice problems are provided for further understanding.
