Answer 1

we were told that in every 4 songs on the playlist, 3 of the songs are longer than 5

so if in for 4 songs, 3 is longer than 5

for 8 songs,

we divide the the number of songs in the playlist by 4 in other to get the numbers of 4 in it then muliply by the number of songs longer than 5

for 8 songs on the playlist:

= 8/4 X 3

= 2 X 3

= 6

For 32 songs on the playlist

= 32/4 X 3

= 8 X 3

= 24

For 40 songs on the playlist

= 40/4 X 3

= 10 X 3

= 30

For 136 number of songs on the playlist

= 136/4 X 3

= 34 X 3

= 102

so in completing the table:

Total Number of Songs on the Playlis Number of songs longer than 5min.

8 6

32 24

40 30

136 102
