# Writing fractions as decimals review

Review writing fractions as decimals, and try some practice problems.

## Writing fractions as decimals

To convert a fraction to a decimal, we divide the numerator by the denominator.
If we have a mixed number, the whole number stays to the left of the decimal.
Example 1: $\frac{2}{5}$
$\frac{2}{5}=2÷5$
$\frac{2}{5}=0.4$
Example 2: $3\frac{7}{8}$
$3$ stays to the left of the decimal. Then, we divide $7$ by $8$.
$\frac{7}{8}=7÷8$
$3\frac{7}{8}=3.875$

## Practice

Problem 1
Rewrite $\frac{3}{10}$ as a decimal.
