Question

there are 24 people in a fitness studio. 3/8 of the people are lifting weights, 1/3 are cross training, and the remaining people are running. what fraction of people are running

Answer 1

7/24

Explanation:

Total people in the studio = 24

3/8 are lifting weights
==> Number of people lifting weights = 3/8 x 24 = 9

1/3 are cross training
==> Number of people cross training = 1/3 x 24 = 8

Therefore the remaining people who are running = 24 - (9 +8)

= 24 - 17

= 7

As a fraction of the total people, this would be

7/24
