Answer
$\frac{3}{10}=.3=30$%
Work Step by Step
We are given the fraction $\frac{3}{10}$.
We know that $\frac{3}{10}=3\div10=.3$
To write $\frac{3}{10}$ as a percentage, we can set $\frac{3}{10}$ equal to $\frac{p}{100}$ (where p is the percentage representation of the given fraction) and take the cross products to solve for p.
$\frac{3}{10}=\frac{p}{100}$
$3\times100=10\times p$
$300=10p$
Divide both sides by 10.
$p=30$%
Therefore, $\frac{3}{10}=.3=30$%.
