27 and 3 can go into 81. 81, and 1 can also go into 81.
4 can go into 81 twenty whole times. After that, the 81 is still not full, but there is onlyenough room left in it for ' 1 ' more, so it is not possible to jam the entire 4 in again.If you're allowed to cut the 4 up in pieces, then you can use ' 1 ' to fill up the restof the 81, and then unobtrusively discard the 3 that you have left over.
Nine can go into both 36 and 81, so the simplest form of 36/81 = 4/9.
