$\frac{15}{64}$
(-$\frac{3}{8}$) $\div$ (-$\frac{4}{5}$) $\times$ ($\frac{1}{2}$) = RECALL: $\frac{a}{b}$ $\div$ $\frac{c}{d}$ = $\frac{a}{b}$ $\times$ $\frac{d}{c}$ Use the rule above to obtan: (-$\frac{3}{8}$) $\times$ (-$\frac{5}{4}$) $\times$ ($\frac{1}{2}$) = Multiply the numerators by each other, and multiply the denominators by each other: $\frac{(-3)\ \times\ (-5)\ \times\ 1}{8\ \times\ 4\ \times\ 2}$ = $\frac{15}{64}$
