How to Find Percent Using a Proportion

The video tutorial explains how to solve a standardized math test question using proportions. The problem involves calculating the percentage of the recommended daily amount of vitamin C Adriana consumed by drinking 2 and 1/4 cups of juice, given that 1/2 cup provides 30% of the daily amount. The solution involves setting up a proportion and solving it using the cross-product property, resulting in the conclusion that Adriana consumed 135% of her daily vitamin C requirement.
