$\frac{122}{63}$

#### Explanation:

First we should get a common denominator. since the common factor of 9 and 7 is 63 ( 9 x 7 = 63) we will write 63 as the denominator.
to get the common denominator, multiply the first fraction by the denominator of the other fraction and multiply the second fraction from the denominator of the first fraction.

then our sum will look like:

$\frac{7 \cdot 2 + 9 \cdot 12}{63}$ $\to$ $\frac{14 + 108}{63}$ $\to$ $\frac{122}{63}$
