Saved a checkpoint:
Looks good!
The part that asks for a fraction also accepts a decimal, but that's a Numbas problem. I've got a long-standing issue on GitHub about acceptable answer formats: https://github.com/numbas/Numbas/issues/380 (this is for my reference only!)

In the advice, it is not conventional that a comma is placed at the end of the line within a derivation or calculation, as you have with something like
\[\begin{align} x &= \frac{1}{10}\text{,} \\ &= 10\%\text{.} \end{align}\]
An appropriate place to have a comma at the end of a line within the align environment is where you have something more like a list:
\[\begin{align} x_1 &= 2\text{,} \\ x_2 &=4\text{.} \end{align}\]
Sorry, this is probably me brainwashing you about punctuation!
Also, your statement is unrelated to the question content, which is really about conversion. You can keep it in, but should expand on it.

In part a)i), you need to untick the box in the marking section that says 'require trailing zeroes'. I just entered $0.4$ instead of $0.40$ and it marked it wrong. I would put a full stop at the end of all sentences such as 'Convert this probability to a decimal'.

- You don't need either of the commas in the second sentence of the statement.
- The question statement of part a) sounds like it should be the first sentence in the advice. It should just be "The probability that it will rain today is 90%."
- i) and ii) should be i) and ii) in italics in both the questions and the advice.
- I think that the bracket after P in both i) and ii) should just say (rain) rather than (it rains today).
- Again in part b), I think it should say "The probability that the bus is late today is 0.7." rather than "You are told that the probability that your bus is late today is 0.7."
- Again in part b), I think the bracket should just say (late) rather than (Your bus is late). Also pointing out that you capitalised this bracket but didn't in part a). I don't know which one is right but you should probably keep it consistent.
- Again in part c), I think it should say "The probability that a football match between Newcastle and Manchester ends in a draw is 1/7." Also, I think you should add United after Newcastle and United/City after Manchester (but preferably United haha) just so the context seems more realistic.
- I would not use "just" anywhere in the advice. It is almost the same as saying "simply" which Christian hates and is a little belittling to someone who is actually finding this difficult.
- I like all the contexts and how you switch the questions around so the user has to be able to convert to all three things! :)

I was going to try and use a few less questions, but i wanted to make sure all directions of conversions were covered. (e.g fractions - decimals and decimals - fractions).

For each combination of answer and choice, specify the number of marks to add or subtract when the student picks it.
For each combination of answer and choice, write 1 if the student should tick it, or 0 if they should leave it unticked.
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:
This is an extension type part. There is no expected answer, and it's assumed that the marking depends on interactions within the part's prompt.
You can test this part's marking algorithm by interacting with the rendering of the part's prompt below.

When you need to change the way this part works beyond the available options, you can write JavaScript code to be executed at the times described below.
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.
This part can't be reached by the student.
Add a "next part" reference to this part from another part.
