make x=.9999999999....
first multiply x by ten = 9.9999999999 (10x=9.999999.....)
then subtract x =9.000000 (9x=9.0000000)
then with simple algebra, solve 9x=9.
since x=.99999.... , .99999... = 1

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

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?
