#### Answer

$= \frac{40}{48}$

#### Work Step by Step

Let $x = $ the denominator
$\frac{x-8}{x} = \frac{5}{6}$
1. Cross multiply:
$6(x-8) = 5(x)$
$6x - 48 = 5x$
$6x - 5x - 48 = 0$
$x - 48 = 0$
$x = 48$
2. Substitute the variable into the original expression to find the fraction
$= \frac{x-8}{x}$
$= \frac{48-8}{48}$
$= \frac{40}{48}$
