Question statement

Add the following fractions using the formula $\dfrac{a}{b}+\dfrac{c}{b}=\frac{\boxed{a}+\boxed{c}}{\boxed{b}}=\frac{\boxed{a+c}}{\boxed{b}}$ .

An example of a correct calculation would be $\dfrac{1}{2}+\dfrac{3}{2}=\frac{\boxed{1}+\boxed{3}}{\boxed{2}}=\frac{\boxed{4}}{\boxed{2}}$ .

Note the final fraction should be left as it is and should not be entered in lowest form (if this is different).

Give any introductory information the student needs.

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

{a}{d} $\ +\$ {b}{d} $\ =\$ Gap 0. $\ +\$ Gap 1. Gap 2. $\ =\$ Gap 3.Gap 4..

Advice

The correct calculation is $\dfrac{\var{a}}{\var{d}}+\dfrac{\var{b}}{\var{d}}=\frac{\boxed{\var{a}}+\boxed{\var{b}}}{\boxed{\var{d}}}=\frac{\boxed{\var{a+b}}}{\boxed{\var{d}}}$ .
