Very curious website...tell me, do most people here believe in dinosaurs?  What about the moon, what is the consesus take on that?

Not only are your questions non-correlational with a flat Earth belief, but you posted them in a thread about a mathematical curiosity. Double fail.

Okay all you internet idiots.
If 0.9999999 = 1.00000000 then I guess
0.8888888 = 0.9999999 and
0.7777777 = 0.8888888 ...

Sounds like everything = 1. You guys could believe in a round earth.

Obviously 0.9999999 ≠ 1.

No.

0.111... = 1/9
0.222... = 2/9
0.333... = 1/3
0.444... = 4/9
0.555... = 5/9
0.666... = 2/3
0.777... = 7/9
0.888... = 8/9
0.999... = 9/9 = 1

As for the millionaire question:

Since 1 million is finite, a better question would be.

If God comes down with an unlimited (∞) amount of money, and he gives some away, how much does he have?

There is nothing subtracted from 1 to get 0.999... because it would have to be 0.000...1.  An infinite number of 0's with a 1 on the end, which is of course impossible.

Umm - you don't need to go into calculus to prove .999999... = 1

Just go back to conversion of decimals to fraction in elementary school.

0.999999999999... * 10 = 9.999999999...

9.999999999999... - 0.999999999... = 9 = 9* 0.999999999999999

9/9 = (9*0.99999999....)/9 = 1

You can do the same thing to convert any repeating decimal to it's fractional expression. Taking at random 0.12345 ...

0.12345... * 100,000 = 12345.12345...

12,345.12345...-0.12345... = 12,345 = 0.12345.. * 99,999

thusly 0.12345... = 12,345/99,999 = 4,115/33,333.

CD. Or maybe in this case QED - <G>

This is always true for any x:
A = 0.[x amount of 9's]
B = 0.4[x - 1 amount of 9's]5
A / 2 = B

ie
0.99 / 2 = 0.495 | x = 2

This means that for any A, there is a B with more digits. In order for A to = 1, x needs to be infinity, as in nothing bigger. Yet there is a B that shows there is another digit. This B is of finite value, which proves there cannot be an A where x = infinity.

QED 0.999999... != 1

0.999... = 3/3

(3/3) / 2 = 3/6

3/6 = 1/2

0.999... / 2 = 0.5

0.099999..*100 = 9.99999...
9.9999...-0.0999..=9.9= 0.099999...*99

Ah - you're right  - I assumed that you made a statement that was actually mathematically legal and that anything that made it look completely outside grammar was a typo, but since you wrote 0.4999...5, which is an undefined statement, and .5 *is* defined, you're quite right.

0.4999...5 = 1/0 = undefined - there, all better now.
