It is not a static answer. I was not aware of the regular expression option,
this is promising and I think I could do either substitution ($frac =~
s/\//\\\//;) or split (@fracarray = split('/', $frac);) and concatenate strings
into the desired regular expression.
Also, I have attempted using an <answergroup> under a <stringresponse> and it
just doesn't recognize it.
Thank you!
