When problems are created using the formula generator, the answers can only be entered as integers or decimals. Many answers do not display well as a decimal and mathematicians will not want answers as decimals most of the time.
I propose that fractions are added as an acceptable format for problems that are created using the formula generator.
This will allow for more accurate answers and prepare students for college and life in a better way.
After consulting with some computer programmers, without knowing the specifics of the code being used, this should be a simple enough feature to implement.
