Question
Multiply: $\frac{-6}{11}\ \text{by}\ \frac{-55}{36}$
✓
Answer
$\frac{-6}{11}\ \text{by}\ \frac{-55}{36}=\frac{-6}{11}\times\frac{-55}{36}$
$=\frac{(-6)\times(-55)}{36}$
$=\frac{(-1)\times(-5)}{1\times6}=\frac{5}{6}$
$=\frac{(-6)\times(-55)}{36}$
$=\frac{(-1)\times(-5)}{1\times6}=\frac{5}{6}$
