So the ratio of shirts before the purchase to the total number of shirts after the purchase is 1:3
Step-by-step explanation:
In this question we have to find the ratio of before and after so It will be written like this
Before : After
11: 33
Dividing both sides with 11
11/11:33/11
1: 3
So the ratio of shirts before the purchase to the total number of shirts after the purchase is 1:3
Which means that if we have total of 4 shirts then the number of shirts before the purchase were 1 and after the purchase were 4 meaning there are 3 new shirts in place for every single old shirt.
