Question

freddy is searching for a shirt and discovers that he has 12 shirts for every 6 pair of jeans. If he has 18 shirts, how many pairs of jeans does he have?

Answer 1

9 pairs of jeans

Explanation:

there are 2 times as many shirts as jeans, and 18 divided by 2=9

Answer 2

12 / 6 = 18 / j.....12 shirts to 6 jeans = 18 shirts to j jeans
cross multiply
(12)(j) = (6)(18)
12j = 108
j = 108/12
j = 9...so when there are 18 shirts, there are 9 jeans
