During a period of 80 minutes, a music station played 8 minutes of commercials. What is the ratio of music they played to commercials they played?

Step-by-step explanation:

80 minutes ... 8 minutes played commercials ... that means (80 - 8) = 72 minutes played music

so the ratio of music to commercials is : 72/8 which reduces to 9/1 ... so the ratio is 9:1 <== = ur answer

* * pay attention to the wording, because if it would have asked for the ratio of commercials to music, it would have been 8/72 ... ratio would be 1:9
