#### Answer

$\frac{1}{3}=.333=33.3$%

#### Work Step by Step

We are given the fraction $\frac{1}{3}$.
We know that $\frac{1}{3}=1\div3\approx.333$
To write $\frac{1}{3}$ as a percentage, we can set $\frac{1}{3}$ equal to $\frac{p}{100}$ (where p is the percentage representation of the given fraction) and take the cross products to solve for p.
$\frac{1}{3}=\frac{p}{100}$
$1\times100=3\times p$
$100=3p$
Divide both sides by 3.
$p=33.3$%
Therefore, $\frac{1}{3}=.333=33.3$%.
