@sammy100189 Thanks for asking! The answer we were looking for is 30. You can divide both 40 and 24 by 4 getting you 10 and 6. Then multiply 6 by 3 to get 18, meaning you could multiply 10 by 3 and get 30. However, if you divide each of them out it is a decimal, so you could round up to 31 purchased songs. I would accept either answer, providing the work was shown to get to the answer.
