I have had a few problems on here where I could have simplified the problem and gotten a mixed number and it's been wrong. ON this particular problem, I didn't simplify to whole digits, and I was wrong. This seems to be inconsistent Either it should simplify to mixed or whole numbers or not. Not back and forth.
