1-99.

Find a common denominator.

$\frac{9}{15} + \frac{5}{15} = \frac{14}{15}$

$\text{By multiplying the first fraction by } \frac{3}{3} \text{ and the second by } \frac{5}{5} \text{ you will achieve a common denominator of 15.}$

Now, you should be able to add the numerators together to get the correct sum.
