Answer

$\frac{5}{3}=1\frac{2}{3} .$

Work Step by Step

We are given: $\dfrac{8}{x}=\dfrac{24}{5}$ To solve the proportion, we cross multiply: Set the product of the means equal to the product of the extremes and solve for x as follows, $$ 24x=8\cdot 5\Longrightarrow x=\frac{8\cdot 5}{24}=\frac{5}{3}=1\frac{2}{3} .$$
