Hello people, heres my worthless two cents.
1 does IN FACT = 0.9 (recurring).
BUT
1/3 does NOT = 0.3 (recurring)
I'm sorry, It just doesn't. Go read a further maths text book.
ACTUAL PROOF would be something like this:
-------------------------------------
lets say x=0.9 recurring.
therefore 10x = 9.9 recurring.
and if we do 10x - x = 9,
therefore x = 1
-------------------------------------
There is absolutely no flaw in that.
