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

taurus [48]

Answer:

$9\ songs$

Step-by-step explanation:

we know that

The slideshow is $31\frac{1}{2}$ minutes long

convert to an improper fraction

$31\frac{1}{2}=\frac{31*2+1}{2}=\frac{63}{2}$

The songs are each $3\frac{1}{2}$ minutes long

convert to an improper fraction

$3\frac{1}{2}=\frac{3*2+1}{2}=\frac{7}{2}$

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

$(\frac{63}{2})/(\frac{7}{2})=9\ songs$
