Hello Everyone!

I would like to ask, what is the solution to this?

I have a Moodle site, and I use Stack. I want create a fraction with user input, like this:

**$\frac{input:ans1}{b}$**

Or this:

**\(\frac{input:ans1}{b}\)**

But, this formula does not works.

I tried more formula, but I couldn't find the solution.

Please help!

Thank you!
