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