• POW #5 Notes


    To answer this problem,think of working "backawrds."  Think of what the previous pile of coconutes must have had in it.  You are basically making a 2/3rd pile, a 1/3 pile and one additional unit (1 coconut) three times.  Say that you found a pile of 4 coconuts,  You could throw one to the monkeys, and divide the remaining pile of 3 into 2/3 (2) and into 1/3 (1).  


    Now think, if you found a pile of four, what did the previous pile (from which it came) look like?
