#### Answer

18/25

#### Work Step by Step

We first put the two whole numbers into fraction form, giving us the following:
$\frac{9}{5} \div \frac{5}{2}$
Because we cannot divide by a fraction, we must multiply the first fraction by the reciprocal of the second fraction. Because the reciprocal of 5/2 is 2/5, we obtain:
$\frac{9}{5}\times \frac{2}{5} = \frac{18}{25}$.
