#### Answer

$\frac{71}{6}$

#### Work Step by Step

To write $11\frac{5}{6}$ as a mixed number, we must multiply the whole number in front of the fraction and the denominator together.
$11\times6=66$
Next, take the sum of the number above and the numerator.
$66+5=71$
This will be the numerator of the mixed number. We will use the original denominator as the denominator of the mixed number. Therefore, $11\frac{5}{6}=\frac{71}{6}$.
