Question

If 5/8 of the people in a water aerobics class are over age 65 and 1/4 of the people in the class are under age 40, what fraction of the people in the class are either over 65 or under 40?

Answer 1

Answer:

7/8

Step-by-step explanation:

You just need to add the two fractions together. Since no one can be both, no  other revision is needed.

5/8 + 1/4 = 5/8 + 2/8 = 7/8
