we  know that

Dividing is the opposite of multiplying. Therefore, dividing by a fraction can be accomplished by multiplying by its reciprocal

so

\frac{\frac{a}{b}}{\frac{c}{d}} =\frac{a}{b}*\frac{d}{c}

in this problem we have

\frac{a}{b}=\frac{3}{5}\\ \\\frac{c}{d}=\frac{3}{15}

substitute in the formula above

\frac{\frac{3}{5}}{\frac{3}{15}} =\frac{3}{5}*\frac{15}{3}=3

therefore

<u>the answer is </u>

3
