9/9=0.111111
0.1111111*9=0.999999999

1=0.999999999

it's 0.999... derp. It's an infinite regression.

How do you divide a number by itself and get 0.1 repeating?

This is how it's done:
x = 0.9 repeating
10x = 9.9999999
10x - x = 9x = 9
x = 1
x = 0.9 repeating

1 = 0.9 repeating

Good thing that's just an intuitive proof and not a riggerous mathematical one, of which there are plenty.

I think you ment 1/9 = 0.999999
otherwise you just said 0.999 = 9

>>2497408
you can if it has absolute convergence, which all infinite decimals do

But he started saying 9/9=0.111111
Which is wrong.
