I've changed the status to "should not be used", as this has been split into separate questions.

I wasn't sure if you still wanted to keep this question or not since you've split it into two seperate questions, but i thought because the content of this question is still different to that in the questions that you have created then i could just rename this question from "Equivalent Fractions" to "Converting between Mixed Numbers and Improper Fractions".

Saved a checkpoint:

In the advice, I don't find the justifications for parts a and b very clear at all. I'd say, for example, "$\frac{3}{18}  = \frac{3}{3} \times \frac{1}{6}$", not "$1 \times 3 = 3$ and $6 \times 3 = 18$ to give $\frac{3}{18}$". The latter looks like it's working backwards. Your worked solution should reproduce the steps a student could take to get to the right answer.

The formatting in the advice for part c has gone awry, with some lines centred that shouldn't be.

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!

'Which fraction is the odd one out?"... the first, because they are one digit numbers? 

I think it's too vague. "Select the fraction which is not equivilant" would be more precise, or if you want to keep the phrase because it's catchy: "Which is the odd one out? Select the fraction which is not equivilant."

In (c) and (d), include $=$ inside the LaTeX.

In the advice you have "time(s)", because the variable round could take the value 1. You could replace this text, making use of the jme function if: {if(rounds=1,"time","times")}.

This variable is an HTML node. HTML nodes can not be relied upon to work correctly when resuming a session - for example, attached event callbacks will be lost, and mathematical notation will likely also break.

If this causes problems, try to create HTML nodes where you use them in content areas, instead of storing them in variables.

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

Test that the marking algorithm works

Check that the marking algorithm works with different sets of variables and student answers using the interface below.

Create unit tests to save expected results and to document how the algorithm should work.

There's an error which means the marking algorithm can't run:

Run this script the built-in script.

This script runs after the built-in script.

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.

Variable Answer to use Must be answered?

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.
