greater than. if the top numbers are the same and the bottom number on one is smaller (i.e. it is divided by less) then it is larger. 5/5 is 1 and 5/8 is less than 1 (0.625)

No solution. If it's less than 5, it can't be as much as 10, so it certainly can't be greater than 10. If it's greater than 10, it can't be as little as 5, so it certainly can't be less than 5.
