Is .99999999 with infinite 9s equal to 1?

Can someone get this straight?

In math, no, in practical computing terms, yes.

But I thought if you had an infinite series it would equal to 1

And since 1/9 is .111111

.1111111x9=.9999999

9/9=1?

No. It does not. - 11-30-2012, 11:02 PMJerry HildenbrandRe: .99999=1
x = 0.999...

10x = 9.999...

10x-x = 9.999... - 0.999...

9x = 9

x = 1 - 12-01-2012, 01:18 AMKizzmocatRe: .99999=1

Nope. You start out already establishing x=.999... The next step is a pointless example that doesn't change anything. The third is right, but the forth is where you messed up. I don't know how you got to that, but that line shouldn't even exist.

Simply worked out, 10x-x = 9. There is no 9x=9 or anything like that. - 02-18-2013, 01:10 PM-darkknight-Re: .99999=1
Hmmm I'm still confused
