Understanding Percent Proportion

This video tutorial explains how to solve percent problems using the percent proportion method. It covers setting up the proportion by writing the percentage as a fraction with a denominator of 100 and placing the 'is' and 'of' numbers in the numerator and denominator, respectively. The tutorial includes an example problem where 86 is calculated as a percentage of 1,720, demonstrating the steps of cross-multiplying and solving for the unknown percentage. The final result shows that 86 is 5% of 1,720.
