Question: 11

Difficulty: medium

If 55% of the purchases were made ONLINE, then the remaining 45% of the purchases were made IN A STORE

What was the ratio of the number of purchases made online to the number of purchases made in a store?
Ratio = 55 to 45

Check the answer choices . . . not there.
Looks like we need to SIMPLIFY the ratio.
Take: 55 to 45
Divide both sides by 5 to get: 11 to 9
