Percent Word Problems Challenge

The video tutorial covers solving percent word problems using proportions. It includes examples such as determining the number of students in a chess club, calculating a grizzly bear's normal heart rate, finding the percentage of planets with moons, and distributing profit from a lemonade stand. Each problem is solved by setting up a proportion, cross-multiplying, and solving for the unknown variable.
