Description

Describe what this variable represents, and list any assumptions made about its value.

Can an exam override the value of this variable?

Generated value: `expression`

d*p*w

← Depends on:

q1numset

This variable doesn't seem to be used anywhere.

Gap-fill

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

(a)

$\var{q1num}$	=	(a) numerator
$\var{q1den}$		(a) denominator

(b)

$\var{q1num}$	=	(b) numerator
$\var{q1bden}$		(b) denominator

When simplifying, remember only common factors can be cancelled.

Advice

Remember that only common factors can be cancelled. Recall that the factors of an expression are multiplied together, not added.

(a): $\var{latex(q1denset[0])}$ is a common factor $\var{latex(q1denset[0])}$ and $\var{latex(q1denset[1])}$ are common factors and can be cancelled.

(b): The numerator and denominator do not share a common factor, so nothing can be cancelled. This fraction cannot be simplified.

Give a worked solution to the whole question.
