I'm pretty sure 9 times .1 repeating is one...

Any number divided by itself is one. Simple Math 101. Still cool to see in a different format though.

also it is not .1 but with a different symbol.
it's the same as saying 9 = y :)

The problem with this proof is that it requires you to assume that 1/9 = .1 repeating. Which is basically what you are trying to prove. Using geometric series as Titan said is probably best.
