Question

Quick!!! (hint- ':' = 'to')

In a sports shop the ratio of large : medium: small vests sold is 3:5:4.
If 15 medium vests are sold, how many large and small vests are sold?​

Answer 1

9 large vests are sold and 12 small vests are sold

Explanation:

the ratio is still equivalent so to get from 5 to 15 you multiply by 3 so you have to multiply 3 and 4 by 3 to to know how many vest the sports shop sold

3:5:4=?:15:?

5x3=15

3x3=9

4x3=12
