Lesson 5 — Rates, Ratios,

and percents


There are many instances in your life that you use rates, ratios, and percents. When you are trying to figure out the cost of one item in a package or when you talk about the number of people on your soccer team compared with the number of balls in the equipment bag, you are using these ideas.


 

In this lesson, you will:

  • express rates and ratios in equivalent forms to solve problems in everyday contexts
  • learn how to express ratios as percents
  • learn how to change a percentage into a decimal form when shopping for items on sale
