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.

I tried to use variables for this question, but i'm not really sure it's possible.

This all looks pretty good, i just have a few suggestions.

Main Parts

a) iii) For a recurring decimal, you could use a handy piece of notation to avoid writing something like 0.6666...

using 0.\dot{6}, you can write the 6 with a dot above it which is the common notation for a recurring decimal. If you do want to use this i would also put a note in the statement saying 0.\dot{6} means 0.666...

Advice

On the first line you say "to convert a fraction into a decimal" whereas this should be "to convert a decimal into a fraction". I also think in this opening paragraph that you should say that you are multiplying the numerator and the denominator of this fraction by 10 instead of just saying that you multiply the whole fraction by 10.

a) iii) I don't think this is really enough of an explanation for how you convert a recurring decimal to fraction. I think there is actually a different method for converting recurring decimals to fractions, see the following link: http://studymaths.co.uk/topics/convertingRecurringDecimalsToFractions.php

a) iv) you haven't entered the decimal that you are converting to a fraction underneath the iv) here as you have with the other questions.

Otherwise, i think this is a good question!
