Question

22/30

Explanation:

Step1: Apply division rule for negatives

Two - negative numbers division gives positive. So, $- 12.6\div(-0.8)=12.6\div0.8$.

Step2: Convert to fraction

$12.6=\frac{126}{10}$ and $0.8 = \frac{8}{10}$, then $12.6\div0.8=\frac{126}{10}\div\frac{8}{10}=\frac{126}{10}\times\frac{10}{8}$.

Step3: Simplify the fraction

$\frac{126}{10}\times\frac{10}{8}=\frac{126}{8}=\frac{63}{4}=15.75$.

Answer:

$15.75$
