Comparing Quantities with Percent

In this lesson, students compare two quantities using a percent. Students use the context of a word problem to determine which of two quantities represents the whole. Students understand that the whole is 100% and think of one quantity as a percent of another using the formula Quantity = Percent × Whole to problem-solve when given two terms out of three from a quantity, whole, and percent. When comparing two quantities, students compute percent more or percent less using algebraic, numeric, and visual models.
