# .9 Repeating Equals 1?

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

For example...(someone wrote):

I'm not really into math, but a friend brought something up to me today that really seemed very strange. (For the duration of this post, .999 will mean .9 repeating unless otherwise specified- just for the sake of ease)

.999=x

10x=9.999

10x - x = 9x

9x=9

1x=1.

.999 = 1.

Someone else wrote:

Numbers are fake. They are a manifestation of our minds to describe something, similar to words. Just because we say "red" doesn't mean something is red. what is red? Languages and math are very similar. Math is universal...at least for our planet though. .999~ does not = 1. But what .999~ repeating represents, does in fact equal what 1 represents.

No-one will ever be able to comprehend infinity, os its time to stop trying. Think of space and the universe. IT IS GROWING. how can it continue to grow with no stop? what is there to contain it? WE need something to contain it in order for us to understand it. We need a stopping point, but there is none.

So who is correct? Do you agree that .999...=1? Or .999... does not equal 1?

active| newest | oldestactually, I barely got a B in my maths test, but I am pretty sure that .999 does not equal one, it is just a tiny bit less correct? but then again, a tiny bit becomes an even tinier bit, and that will keep happening until it gets to 1, except it can't quite get to 1, because the size of something is infinite, big or small. this should be question of the month.

.999... is infinitesimally smaller than 1 yet it remains smaller.

However, 1/9=.111...

so 9/9=1, yet .111...x9=.999...

it is a mathematically unanswerable question, as there are mathematical proofs supporting both answers.
