Answer
0.38
Work Step by Step
Recall the following rule: $\frac{a}{b} \div \frac{c}{d}=\frac{a}{b} \times \frac{d}{c}$.
We convert the decimal into a fraction for the ease of simplification:
$-0.266\div(-0.7)$
=$-\frac{266}{1000}\div-\frac{7}{10}$
=$-\frac{266}{1000}\times-\frac{10}{7}$
=$-\frac{266}{100}\times-\frac{1}{7}$
=$-\frac{38}{100}\times-\frac{1}{1}$
=$\frac{38}{100}$
=$0.38$
