• MAIN PARTS
• Typo in the statement - "bellow" instead of "below".
• Part v) gave me "1ab" as one of the terms. Maybe make sure the 1 cancels.
• I think part b) sounds a little complicated when it is your friend. I suggest you make it yourself or a specific person, eg. Jim. "Jim has a fondness of handmade sweets and is trying to work out the amount of money he has spent on them in one week. He eats [blah] lollipops, [blah] toffees and [blah] jelly sweets. Lollipops cost [blah], toffees are £1 more expensive than lollipops and jelly sweets are half the price of toffees."
• Make sure all your i), ii)... are in italic in both the main question and the advice.
• i) in part b) - "it's" should be "its" and "simplist" should be "simplest". I also think you should specify not to have brackets in your answer. 
• ii) in part b) - I think you should just say "If the cost of a lollipop was [blah], calculate Jim's total expenditure on sweets for the week." I also think you should put a pound sign before the gap fill as the units are pounds.
• Issue with numbas not acccepting answers as terms are in a different order to that which it is expecting. Maybe in the question, specify which order to put the terms to avoid this happening.
• ADVICE
• In parts vi), vii) and viii), I think I would add a line expanding out the brackets to make it more clear. 
• I think the advice for b)i) could be more helpful rather than just telling them to read carefully! Explain how (x+1) means toffees are £1 more expensive etc. 
• Part b)ii), I think you could write "Using the equation we had devised from part b)i), we can substitute the price of lollipops, x=2, to calculate Jim's total expenditure."
• Good question, I like it!

• I don't think that the 6 in 6-sided dice should be in latex form personally. 
• In the advice, you have spaces between the hyphens of 6-sided the second time you mention it but not the first. 
• "teachers" should be "teacher's" and I think I would say "that the teacher's class is comprised of 20 girls." rather than "that the teacher's class is a class of 20 girls."
• I think I would say "Therefore" instead of "So" in the advice.
• Good use of bold in the advice, picking out the key bits of information.

I totally agree with Elliott's feedback about notation of recurring decimals but I can't seem to make it work when the recurring decimal is a variable. 

Also, in some instances, weirdly, simplify doesn't seem to be working for some of the final answers.

It won't let me put visibility conditions on it. :(
