Answer

$\dfrac{8}{35}$

Work Step by Step

The quotient of two negative numbers is positive. Use the rule $\frac{a}{b} \div c = \frac{a}{b} \times \frac{1}{c}=\frac{a}{bc}$ to obtain: $\require{cancel} \\-\frac{24}{35} \div (-3) \\=-\frac{24}{35} \times \frac{1}{-3} \\=\frac{-24}{35(-3)} \\=\frac{\cancel{-24}8}{35\cancel{(-3)}} \\=\frac{8}{35}$
