Answer:
12 sweaters
Explanation:
Given data
We are told that there are 5 shirts for every 4 sweaters
If there are 15 shirts
We want to find the number of sweaters
for 5 shirts there are 4 sweaters
for 15 shirts there are x sweater
Cross multiply
15*4= 5*x
60= 5x
divide both sides by 5
x= 60/5
x=12 sweaters
Hence there are 12 sweaters
