The fraction is (5-x)/5. However, this assumes he paints uniformly throughout all 5 days. All we know is that he can paint the barn in 5 days, but its possible that one half of the house takes 4 days to paint and the other half takes only 1 day, for whatever reason. So there is a lack of information to properly solve this puzzle.

Having encountered many problems of this type in my teaching career, niformity is assumed. Calculus is the proper domain of non-linear change.
