$\frac{-2}{7}$
1. We need to expand the parenthesis first. Keep in mind that multiplying 2 negatives makes a positive $\frac{-9+24\div24}{36-48\div6}$ 2. Then we need to do division: $\frac{-9+1}{36-8}$ 3. Then subtraction: $\frac{-8}{28}$ 4. Finally we can simplify this by diving both sides of the fraction by 4; $\frac{-2}{7}$
