I have deleted the part d) from this question and added in a much simpler question on squaring fractions.

This looks good, but part d seems vindictively hard! What's it assessing?
From the advice, it looks like:
 BODMAS  this isn't what the question's about
 Squaring fractions  have a smaller question on this earlier, e.g. "calculate $\left(\frac{a}{b}\right)^2$".
 Division of fractions  again, not what the question's about.
I reckon you could just delete part d, or spin it into a separate question.

Hi Lauren,
It seems that the answer to part c is rewarded 0 marks, i would maybe just reward 2 marks to this part as you have with the other parts.
Also, for part c, i would write "days" next to the answer box, just so it's a bit clearer what the units of the answer are.
I think there is also a slight issue in the advice section for part b, as sometimes the first fraction \displaystyle\simplify{{k}/{j}}, simplifies too much, for example i saw that number as 5 but i think the intended number was 15/3 because then later in the code when you are multiplying the numerators and denominators of both fractions this shows 15 x \var{numif} and 3 x \var{h}, so because the question shows the first fraction in it's simplified form, it's not immediately clear where the other two numbers come from. To fix this, i would maybe set the gcd of k and j to be equal to 1.
Let me know if you have any questions, otherwise i think it looks good!

Thank you for the feedback. I have enacted your suggestions and corrected the mistakes.

I would change the staement to say something like 'evaluate the following multiplications, giving each fraction in its simplest form'.
In part b), the expected answer is incorrect. When I tried it, the fraction in its lowest terms was $\displaystyle\frac{81}{104}$ but the expected answer said $\displaystyle\frac{162}{208}$. The correct answer appears in the advice though.
In part c) the fractions $\displaystyle\frac{3}{7}$ and $\displaystyle\frac{1}{3}$ should be variables. I know you've picked these numbers so that the answer always comes out as a whole number of days, which of course it must, but it would be much better to get Numbas to produce the variables so that the sum will always work out nicely, otherwise students can only do the question once. Also, display these fractions using \frac.
In the advice, you tend to use colons before stating a result. For example, '...final answer is: $\displaystyle\frac{81}{104}$'. You don't need the colon here, just give the number.

To account for errors made by the student in earlier calculations, replace question variables with answers to earlier parts.
In order to create a variable replacement, you must define at least one variable and one other part.

The variable replacements you've chosen will cause the following variables to be regenerated each time the student submits an answer to this part:
These variables have some random elements, which means they're not guaranteed to have the same value each time the student submits an answer. You should define new variables to store the random elements, so that they remain the same each time this part is marked.
