Answer
$\frac{2}{3}=.667=66.7$%
Work Step by Step
We are given the fraction $\frac{2}{3}$.
We know that $\frac{2}{3}=2\div3\approx.667$
To write $\frac{2}{3}$ as a percentage, we can set $\frac{2}{3}$ equal to $\frac{p}{100}$ (where p is the percentage representation of the given fraction) and take the cross products to solve for p.
$\frac{2}{3}=\frac{p}{100}$
$2\times100=3\times p$
$200=3p$
Divide both sides by 3.
$p=66.7$%
Therefore, $\frac{2}{3}=.667=66.7$%.
