Equation: $\frac {-3}{5} \times \frac{2}{3}$ + $\frac{6}{20} \div \frac{12}{-30}$

Step 1:

$\frac{6}{20} \div \frac{12}{-30}$ —> $\frac{3}{10} \div \frac{4}{-10}$ —> $\frac{3}{10} \times \frac{-10}{3}$ —> $\frac{3}{1} \times \frac{-1}{4}$

$\frac{-3}{5} \times \frac{2}{3}$ + $\frac{-3}{4}$

Step 2:

$\frac{-3}{5} \times \frac{2}{3}$ —> $\frac{-1}{5} \times \frac{2}{1}$

$\frac{-2}{5}$ + $\frac{-3}{4}$

Step 3:

$\frac{-2}{5}$ + $\frac{-3}{4}$ —> $\frac{-8}{20}$ + $\frac{-15}{20}$ = $\frac{-23}{20}$ or -1 $\frac{3}{20}$
