You can put this solution on YOUR website!
Assume you mean:
A picture measure 7 1/2 inches by 5 inches is enlarged so that the larger side become 18 inches.
What does the shorter side become?
:
Let w = the enlarged shorter side
:
Write a ratio equation:
5%2F7.5 = w%2F18
cross multiply
7.5w = 5 * 18
7.5w = 90
w = 90%2F7.5
w = 12 inches is the enlarged shorter side
