At East Middle School, 25% of the 60 students Mrs. White teaches buy their lunches in the cafeteria. How many students purchase their lunch in the cafeteria?

15

Step-by-step explanation:

Whenever you see 25% of something, divide the original number by four. Because 25x4=100, you can use this equation. 25% of something is always your original number divided by four. In this case, the original number is 60. 60 divided by four is 15.
