#### Answer

$\frac{2x}{13}$

#### Work Step by Step

$\frac{\frac{3x}{4}}{5-\frac{1}{8}}$
$=(\frac{3x}{4})\div({5-\frac{1}{8}})$
$=(\frac{3x}{4})\div({\frac{40}{8}-\frac{1}{8}})$
$=\frac{3x}{4}\div{\frac{39}{8}}$
$=\frac{3x}{4}\times{\frac{8}{39}}$
$=\frac{x}{1}\times{\frac{2}{13}}$
$=\frac{2x}{13}$
