Question

The ratio of the number of cars to vans in a parking lot is 8:3 and the ratio of the number of motorbikes to vans is 2:5. If there are 15 motorbikes find the number of cars.​

Answer 1

Answer: Number of cars = 100

Explanation:

Ratio given:

`(Cars)/(Vans) =(8)/(3)`

`(Motorbikes)/(Vans) =(2)/(5)`

Find cars if motorbikes = 15

`(15)/(Vans) = (2)/(5)`

`Vans = (75)/(2)`

Vans = 37.5

using the ration of cars to vans:

`(Cars)/(37.5) =(8)/(3)`

Cars = 100
