Yes, 0.999999999............... does equal 1.

Let's use a simple algebraeic equation.

Let c = 0.999...

10c= 9.9999.....

10c -c = 9

9c/9 = 1.

c = c

1 = 0.999...

If you knew the answer what was the point of this thread...

 

 

Wrong again, once you multiply c *10, theoretically at the end of the infinite 9's there would be a zero.  Which is why 9.... or 9-bar is not .9999999 infinite, it's a symbol for a number that can't be expressed in decimal terms.
