Question

If the ratio of shirts to jeans 5:2 and number of shirts are 15 what is the the number of jeans

Answer 1

6 jeans

Explanation:

ratio of shirt to jeans = 5:2

shirt = 15

jeans = ??

ratio and proportion:

5 shirt = 15 shirts

2 jeans x jeans

cross multiply:

15 (2) = 5 (x)

x = 30 / 5

x = 6 jeans

Answer 2

We are given that the ratio of shirts to jeans is 5 : 2

This means that for every 5 shirts, we have 2 jeans

it also means that the number of shirts / number of jeans = 5 / 2

Since we are given the number of shirts,

we can easily find the number of jeans

(15) / (number of jeans) = 5 / 2

Number of Jeans = (15) * (2 / 5)

Number of Jeans = 6
