Answer:
[tex]9\ songs[/tex]
Step-by-step explanation:
we know that
The slideshow is [tex]31\frac{1}{2}[/tex] minutes long
convert to an improper fraction
[tex]31\frac{1}{2}=\frac{31*2+1}{2}=\frac{63}{2}[/tex]
The songs are each [tex]3\frac{1}{2}[/tex] minutes long
convert to an improper fraction
[tex]3\frac{1}{2}=\frac{3*2+1}{2}=\frac{7}{2}[/tex]
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
[tex](\frac{63}{2})/(\frac{7}{2})=9\ songs[/tex]
