Use division to convert a fraction to a decimal
Change the mixed number to an improper fraction then divide the numerator by the denominator.
$3\frac{1}{4} = \frac{13}{4}$
$\ \ \ \ \ \ \ 3.25$
$4\overline{ )\ 13.00}$
$\ \ \ \ \ \underline{12}$
$\ \ \ \ \ \ \ 10$
$\ \ \ \ \ \ \ \ \underline{8}$
$\ \ \ \ \ \ \ \ \ 20$
$\ \ \ \ \ \ \ \ \ \underline{20}$
$\ \ \ \ \ \ \ \ \ \ \ 0$
Use proportions to convert a fraction to a decimal.
Change the mixed number to an improper fraction
$3\frac{1}{4} = \frac{13}{4}$
$\frac{13}{4} = \frac{x}{100}$
$4x = 13\times100$
$\frac{4x}{4} = \frac{1300}{4}$
$x = 325$
