There is a town that wishes to expand their fountain to twice it's size, but there's a problem. The fountain is square, and arranged with a tree at each corner. The town doesn't want to pay to have the trees removed,so how can they double the fountain's size, while removing the least amount of trees?

i explained it kinda confusingly (is that a word???)
ill try again:
x=0.999999....
first do 10x
10x= 9.9999999999999
then do 10x-x
10x-x=9x
9.9999999 (ten x part)-0.999999999 (x part) = 9.000000 (which is 9x)
since 9x=9, x=1
since x=0.9999999, 0.999999=1
here is the other solution. its easier to explain:
ok..
take 0.999999 and divide it by 3
0.9999999/3=0.3333333333333
convert 0.3333333333... into a fraction
0.3333333333333 = 1/3
now multiply that by 3. that equals one
1/3 X 3 =1
explanation is bolded. not bold = math

does the fountain with the doubled size still have to be square?
