Answer:
The fraction of the deposit is;
[tex]\frac{3}{100}[/tex]Explanation:
Given that a bank deposit of $300 earned $9 interest.
[tex]\begin{gathered} \text{Deposit D= \$300} \\ \text{Interest I = \$9} \end{gathered}[/tex]The fraction of the deposit is;
[tex]\begin{gathered} f=\frac{I}{D}=\frac{9}{300}=\frac{3}{100} \\ f=\frac{3}{100} \end{gathered}[/tex]Therefore, the fraction of the deposit is;
[tex]\frac{3}{100}[/tex]
