Question

During a period of 112 minutes, a music station played 40 minutes of commercials. What

is the ratio of music they played to commercials they played?

Answer 1

9:5

Explanation:

1. 112 - 40 = 72. 112 represents the total time, but you are comparing music to commercials, so you have to subtract the commercial time from the total time.
2. Find the GCF of 72 and 40, which is 8.
3. Divide 72 and 40. The simplified ratio is 9:5.
