most of you seem to have a crude sense of "infinity"

.99999....... represents the infinite sequence of...well, exactly what it says - .9 + .09 + .009.......

by the least upper bound axiom of real numbers, this sequence is equal to 1

too many people think .9999999.... repeating is just a bunch of nines after the decimal point

.99999..... does not equal 1. It can be rounded up to 1, or if you add .000000000000000000000000000000000000000000001 then yes, it will be one, but in the end, without adding or rounding, it is not one.

This is like saying that does 30 = 50? No, it does not.
20.9=21? No it does not

35=11234? No, it does not.

All numbers have a specific place on the number line. They will stay on that spot, until you add or subtract from that number. Otherwise, they cannot magically shift, unless God wants it to move. :D

Bing bang boom, solved this question :D

Not quite. What is the number inbetween 0.99999... and 1?

If there is no number inbetween then it must equal 1!

Also, look at the other proofs like the x 0.9999... changes to 10x and goes back to x to equal 1.

Nice try, but on the number line (which is the most important factor here) 1 is 1.000000000000000000000000....
.999999999999999999.... just gets closer and closer and closer and closer to 1, but never actually hits it.

Just because there is no number between does not mean they automatically equal each other. they can be next to each other -.-

Proofs like that end up rounding just the slightest. The proof may round up to the nearest 1000th, and in that case, it would indeed be 1.

There, now you get it! You now agree with everybody else that the 0.99999999999999....... does indeed equal 1!

You have been cleansed!

Lol, I said that it would equal one if it was to be rounded, like I do on my worksheets lol.
But in theory it does not equal one. It's an infinite, nearing 1. :D

It also does equal 1.

33%
66%
100%

3 people only can win a race, they all have 1/3 chance, or 33%

Even if it does add up to 99% who else gets the 1% huh?

Lol, I'm starting to get why this topic is soooo gay :D.

Let's look at this way.

You have a piece of bread.
You slice off .000000000000000000000000000000000000000000000000000000000000000000000001 % of the piece of bread and pull it away. Do you have the whole piece of bread?
Answer is no, you do not.

The 1% percent is null, in my opinion. the 1 % stands for if they all die and don't make it to the end. It stands for the unlikely :) hence the small percentage.
Lol, I'm enjoying this :D
