I think this is a good question, it is reasonably challenging and well constructed.

Main Parts

a), b) I think you should add a hint for the precision required, even though i know the units are in pounds and there only should be two decimal places, but i would still include a hint saying give your answer to two decimal places.

b) i'm not entirely sure about this but i don't think the steps you give here are entirely relevant, as the steps show an increase in money every year whereas the question is about money decreasing monthly.

Advice

a) I would say "This is the money we would get if we withdrew the whole savings balance today" instead

b) you have an & where there should be a %

When you say "we multiply the original price of the smartphone by our multipliers 12 times", i think this should be "multiplier" (singular) and then "as there are 12 months in a year" rather than "as there is 12 months in a year"

a) and b) i think you should add a £ symbol to your final answers in the advice section just to make it clear that this is an amount of money.

Otherwise, this looks pretty good!

Will try to add an image from inkscape to this as well, but just thought i'd set its status to "Needs to be tested" in the meantime.

I think this question is really good and works well. I just noticed a few grammatical things that might need to be changed.

Main Parts

a) good

b) good

c) good, but i think you should say "reduce them down to their simplest form" instead of "reduce down to their simplest form".

d) the i and ii should be in italics as they are in part c) (maybe shouldn't be bold too).

Not entirely sure, but i think there should be full stops after each of the fractions with the gaps on them in parts c and d.

Advice

I can't tell if you have done this or not, but it might be worth checking that when you are typing the a), b), c) etc in the advice, that you are just setting the format of each of them to "heading 4" and not making them bold as well.

I think "was" should be "is" in a) and b)

I would get rid of the "and", after the semi-colon, on the fifth line of a)

In c),

I think you need to add a line of text before your definitions of improper fractions and mixed numbers, for example i would write

"A mixed number is a number consisting of an integer and a proper fraction,

I.e a number of the form

a (b)/(c) where a is an integer and b/c is a proper fraction"

In d),

in i) and ii) i would add an extra line after you say what the new numerator of the proper fraction is. I think you need to simplify the proper fraction first before combining it with the integer to form the mixed number. I would say "Therefore, the proper fraction is ...". Then simplify it and then combine the simplified proper fraction with the integer at the end. Also, i think when you give the final answer i think you should put the improper fraction that you are changing before it to make the full transformation clear, e.g 13/6 = 2 1/6.

I would also change "This is in this question" to "In this question, this is".

Otheriwise, this looks good!
