1 = 0,99........

However weird this might sound 1 is equal to 0,99....(infinite 9s)

Proof (note that 0,9~ = 0,99......):

x = 0,9~
10x = 9,9~ (multiplied by 10)
10x - x = 9,9~ - 0,9~ (substracted x)
9x = 9
x = 1
1 = 0,9~


A more analytical proof is:

EDIT: Simple and Practical version by Unearthlybrutal

Simply version

1 / 3 = 0.33333... (infinite 3)
Then:
0.33333... x 3 = 0.9999999... (infinite 9)

(1 = 0.99999999...)
•I have found the answer to the universe and everything, but this sign is too small to contain it.
