Answer
$\dfrac{10}{3}$
Work Step by Step
$\frac{a}{b} \div \frac{c}{d} = \frac{a}{b} \cdot \frac{d}{c}$
Use the rule above:
$\frac{5}{4} \cdot \frac{8}{3}$
Cancel the common factors:
$\require{cancel}
\\=\dfrac{5}{\cancel{4}} \cdot \dfrac{\cancel{8}2}{3}$
Multiply the numerators together and the denominators together:
$=\dfrac{5(2)}{1(3)}
\\=\dfrac{10}{3}$
