Simple maths question.
1/3 = 0.333333.....
3*0.3333....=0.999999999......
1/3*3=3/3
=1
Hence 0.999999.....=1.
Is this correct?
Yes and no.
It doesn't really equal 1, just shows how math can be flawed.
Pretty much. I wanted to cut my teacher's head off when he told us that.
yes because 1 divided by 3 gives 0.999999 ... to infinity so 3*1/3 adds 1/3 making it 3/3 so 1
short answer: yes
Technically yes. Periodical decimals is a property of math.
0.33333 Repeating doesn't exactly equal 1/3 if I'm not mistaken.
wow. 6 replies in less than 2 minutes :o
Wikipedia also has a load of good methods for proving it as well.

Can I ask your age?
Fuck me, I said something stupid. Snip.
ray can you stop posting on facepunch?
please?
Has no one ever heard of rounding up?

It's so very close to 1 that for all intents and purposes it is 1.

This is what I was thinking.
[QUOTE=DanTehMan;17139050]Can I ask your age?[/QUOTE]
err? wth is that for. he gives a correct answer.
and wikipedia is not the only source. google for 1/3 and you won't find a lot, you will find 1 thing:

That's basically what I was getting at lol
Everybody here is really good at math you should go into a profession at this.
Rounding up. A fraction such as 1/3 can never be properly displayed as a decimal, and therefore can never be properly multiplied as a decimal because it's infinite. So in essence it is 1, but it is not .999999.
By the way, a line over the number(s) that repeat infinity in a decimal signifies repetition. So it would be .9 with a line over the 9.

Except we stop rounding up in math in 4th grade

or just 1/3
Oh boy i remember the WoW OT discussions on this...
The correct answer is already posted, 1/3 does not = .3333333, it's just as close as we can get with numbers.
I also heard that digit minipulation proves this quite well

Ahahaha no.

Agreed.
0.33333333 to infinity does not equal one third exactly, but it's as close as you can get using decimals.
3 x 1/3 = 1
3 x 0.333333... = 0.999999...
1/3 =/= 0.333333...
So therefore, no, 0.999999... does NOT equal 1.
this is also [url=http://www.google.com/search?q=1*0.99999999995]1*0.99999999995=1[/url] rounds up..
[QUOTE=roelof;17139203]or just 1/3[/QUOTE]
Uhhh ok. My point was that infinity repeating decimals can only be multiplied correctly with fractions. So basically you supported my statement?
