Answer 2

Answer:

21 minutes

Step-by-step explanation:

I'll show you two way of solving:

1) Using division and multiplication with the given information

We can find out how many times 210 minutes is more than 30 minutes.

210/30 = 7

210 minutes is 7 times 30 minutes.

If for 30 minutes of music it needs 3 minutes of commercials, then for 7 times as much music played it needs 7 times the time of commercials.

7 * 3 minutes = 21 minutes

Answer: 21 minutes

2) Proportion

3 minutes of commercials is to 30 minute of music as x minutes of commercials is to 210 minutes of music

3/30 = x/210

Cross multiply.

30x = 3 * 210

Divide both sides by 30.

x = 3 * 210/7

x = 3 * 7

x = 21

Answer: 21 minutes
