Answer 1

The ratio of rock music to total songs the gissel owns is 25 to 40.

aj has 50 rock songs. Also, the ratio of rock music to total songs in ajs collection is equivalent to the ratio of rock music to total songs that gissel owns. So, we write

`\begin{gathered} (25)/(40)=(50)/(x) \\ x=50*(40)/(25) \\ x=80 \end{gathered}`
