Answer:
hello
we can think like the hamburger is all equal to 100.
if the first bite was %20 of the hamburger, we can say there left 80. because 100×20/100 its = 20 and 100-20= 80. the problem is not this i wanna say. there was a teory similar like this problem.
a girl was going to her home. in every step she was going 2/1 of the road.. it was impossible to arrive to home.
we said 100 for all hamburger right?
it would be 0,0000000100 too..
so if we continued to dividing by %20 everytime, we never had a result of it.
maybe at least we found 0,0000000000001.
And? then we had to found 0,0000000000001's %20.
soo, the problem's answer is its not possible.
good luck(: (sry for nub eng)
