Question

Marcus is picking songs to play during a slideshow. The songs are each 3 1/2 minutes long. The slideshow is 31 1/2 minutes long

Answer 1

9

Explanation:

Answer 2

`9\ songs`

Explanation:

we know that

The slideshow is
`31(1)/(2)` minutes long

convert to an improper fraction

`31(1)/(2)=(31*2+1)/(2)=(63)/(2)`

The songs are each
`3(1)/(2)` minutes long

convert to an improper fraction

`3(1)/(2)=(3*2+1)/(2)=(7)/(2)`

To find the number of songs that Marcus is picking to play during a slideshow, divide the slideshow by the long of one song

so

`((63)/(2))/((7)/(2))=9\ songs`
