Fractions in CL

Maybe this thread will help:

Answer that is a fraction

I can use CL to check non-repeating decimals, but not fractions. After reading through other posts I tried 5\frac{1}{3}. I tried adding \ and \ in front as well as a tick mark, but nothing works. I also want it to show correct if students type 16/3. What am I missing in the code?
