#### Answer

$\frac{34}{5}$

#### Work Step by Step

To write $6\frac{4}{5}$ as a mixed number, we must multiply the whole number in front of the fraction and the denominator together.
$6\times5=30$
Next, take the sum of the number above and the numerator.
$30+4=34$
This will be the numerator of the mixed number. We will use the original denominator as the denominator of the mixed number. Therefore, $6\frac{4}{5}=\frac{34}{5}$.
