Ask the student a question, and give any hints about how they should answer this part.

Write the mixed number as an improper fraction and reduce it down to its simplest form.

$\displaystyle{\var{f}\frac{\var{g_coprime}}{\var{h_coprime}}} =$ Gap 0. Gap 1. .

Advice

A mixed number is a number consisting of an integer and a proper fraction, i.e. a number in the form $a \displaystyle \frac{b}{c}$ where $a$ is an integer and $\displaystyle\frac{b}{c}$ is a proper fraction: $b$ is smaller than $c$ .

An improper fraction is a fraction where the numerator is larger than the denominator, i.e. a number of the form $\displaystyle\frac{d}{e}$ where the numerator, $d$ , is greater than the denominator, $e$ .

To convert a mixed number into an improper fraction, multiply the integer part of the mixed number, $a$ , by the denominator, $c$ .

The numerator of the improper fraction will be equal to this added to what was already on the numerator of the proper fraction.

The denominator of the proper fraction will stay the same when it converts to an improper fraction to give a final answer of

$\displaystyle\frac{({a}\times{c})+b}{c}$ .

${\var{f}\frac{\var{g_coprime}}{\var{h_coprime}}} = \frac{({\var{f}}\times{\var{h_coprime}})+{\var{g_coprime}}}{{\var{h_coprime}}}=\simplify{{num}/{h_coprime}}\text{.}$
