## 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: $\dfrac25$
$\dfrac\blueD2\greenD5 =\blueD2\div\greenD5$
$\dfrac\blueD2\greenD5 =0.4$
Example 2: $3\dfrac78$
$\redC3$ stays to the left of the decimal. Then, we divide $\blueD7$ by $\greenD8$.
$\dfrac\blueD7\greenD8 =\blueD7\div\greenD8$
$\redC3\dfrac\blueD7\greenD8 =3.875$

## Practice
