Question

A radio station requires DJs to play 3 commercials for every 18 songs they play. What is the unit rate of songs to commercials?

The unit rate is

( ???) songs
------------------
1 commercial
.

Answer 1

6 songs

The way to find this answer is to divide 18 by 3, which is six, which means that after every six songs a commercial is played. 

Hope this was helpful and that I explained it correctly.
