$\frac{80}{-6.5}$
1. We always need to expand the parenthesis first, remember that multiplying 2 negatives makes a positive: $\frac{-20+60+40}{4+27\div-6-6}$ 2. Division comes next, so:$\frac{-20+60+40}{4-4.5-6}$ 3. We finish up by doing addition and subtraction, working from left to right: $\frac{80}{-6.5}$
