Understanding Percent Problems

In this video, Mr. J explains how to solve percent problems using the percent equation. The focus is on finding the whole when given a part and a percent. Two examples are provided: one where 12 is 80% of an unknown number, and another where 55% of an unknown number is 33. The video demonstrates converting percentages to decimals, setting up equations, and solving for the unknown variable using division.
