We are using Moodle 1.7
There is a great deal of inconsistency in the display of fractions. The Multiple choice questions translate the code perfectly in the question text and choices.
The Matching questions translates the code in the question text, but not in the choices.
The Cloze question refuses to translate the code in the text and the blanks.
Has anyone found a solution to this problem?
Hi Joseph
This is the code for a fraction that works well in the Multiple choice
$$\frac{365}{365}$$= (you'll need to see this as this forum is converting it to the fraction) I'll explain: Double dollar signs back slash then 365 within curly brackets twice followed by double dollar signs.
When I put it into the CLOZE or the options in MATCHING
I get frac365365 not 
=
That is what I find puzzling. How can the code work in the MULTIPLE CHOICE question, but not at all in CLOZE and not in the choices in MATCHING?
Your help is appreciated.

Hi Daphne,
There is no C.M.S. that I know which would allow you to enter fractions like the one you mention or complicated mathematical expressions in any modest one line of a drop-down menu. What all systems do when the matching options are large objects (images for example) or expressions that are different from a simple one-liner ASCII text (like the math expression that you are trying to type) is to list the options in a reference table with letters as labels (a, b, c, ...), and then give those letters as the matching options of the dropdown menu. I appended below some examples (from different CMS's) on how such questions are generally adapted to use "a, b, c, ..." labels for matching questions.
Note: There are some "Math" UNICODE characters that can help you to enter some Math symbols in the dropdown menu, but the list is finite and for certain will not include the variety of fractions that you need. This is the link that Jeff Forssell kindly gave me http://www.atm.ox.ac.uk/user/iwi/charmap.html (look for the list #22 that contains Math symbols)
Hope this helps...
Cristina you are a gem!
What a lot of time you have spent writing me that most useful answer!
I understand what you are saying about adapting the questions and will rephrase our questions accordingly.
One last question: Why does the code work in Muliple choice, but not in CLOZE? After all it is not in a drop-down menu.
The site sent by Jeff Forssell makes it so easy to get the right UNICODE characters. Thank you for passing it on.
Appreciate your help very much
Sincerely
Daphne
In the Multiple choice. I would like to enter one choice as a fraction (see below):
This works in the question area but not in the choice fields.
I am new to HTML tags and have recently found the answer to Superscripts by using the HTML tag
<sup>...</sup>
Which worked a treat. Is there an HTML tag that will help me with fractions?
Hello Daphne,
Regarding the CLOZE type question problem you encounter, you may want to read the postings on this forum on the topic: "CLOZE type question not accepting TEX notation." Here I give you the link hope it helps since there is exactly a mention on how to write a fraction in a "CLOZE" type question.
Joseph Rezeau gives in detail what you need to change in the code. It worked absolutely fine for me.
Have fun!
Cristina
Thanks Cristina
I'll give it a go and let you know what happens
Daphne
