Olivia and Dillon rain laps after school to train for the cricket team. The ratio of the number of laps of the number of laps Olivia rain to the number Dillion ran was 5 to 2. If Olivia ran 15 laps how many laps did Dillion run?

6 laps

Explanation:

The ratio of the number of laps of Olivia ran to the number Dillion ran

Olivia : Dillion = 5 : 2

Olivia = 5

Dillion = 2

If Olivia ran 15 laps how many laps did Dillion run?

Let x = number of laps Dillion ran

5 : 2 = 15 : x

5 / 2 = 15 / x

Cross multiplication

5*x = 2*15

5x = 30

Divide both sides by 5

x = 30/5

= 6

x = 6 laps

Therefore, Dillion ran 6 laps
