Mar 9, 2017

$\frac{15 c + 12 a c}{a}$

#### Explanation:

You would simplify and sum:

$\frac{15 \cancel{a} \cancel{b} c}{{a}^{\cancel{2}} \cancel{b}} + \frac{12 \cancel{a} \cancel{b} c}{\cancel{a} \cancel{b}}$

$= \frac{15 c}{a} + 12 c$

It is equivalent to the one fraction:

$\frac{15 c + 12 a c}{a}$
