You are downloading songs to your tablet. Th e ratio of pop songs to rock songs is 5 : 4. You download 40 pop songs. How many rock
songs do you download?

The ratio of pop songs to rock songs you download is 5:4, and 40 are pop songs. You want to find out how many rock songs there are.

First, add the ratios together: 5+4=9. This means that 9 will be your denominator, so 5/9 songs are pop and 4/9 songs are rock.

Now you know that pop songs account for 5/9 of the songs, this means that 40 is 5/9 of the total songs.  

To find out how much 4/9 is, you need to divide 40 by 5 to get 1/9 and times that number by 4 to get 4/9:

40÷5=8×4=32 songs are rock songs
