I am going to ask a rather noobish question. In terms of the correct solution show to the student, after the assignment is turned in, is there a way to prevent long decimals to appear in that in favor of fractions?

Assuming I am authoring the problem myself that is.

possbily nothing completely automatic (unless the entire problem has been in Fractions). There are lowlevel macros in PGbasicmacros.pl that help you display decimals, so you can limit the decimal display to only a certain number of significant places. I believe that you can also do this when defining a Context  although I would have to check on that. There are contexts that enforce fractions for answers and through out the problem.

typing Fractions into the search blank on the wiki will give you a number of examples where the problem is to have the students enter fractions in a certain way.

The other relevant fact is that if you use something like Compute(" 4/5") then the correct answer will be displayed as 4/5 and not as 0.80 although the latter will be accepted as a correct answer. This is why Compute("4/5") might be superior to

Real(4/5) which would display the answer as 0.80

The low level formatter in PGbasicmacros.pl is called spf($number, $format) and is essentially front end for sprintf() in perl or C.
