but but as a fraction .49repeting= 49/99
it's been so long since all that math day ******... or calc
Edit virtualgames0 is right .494949494949... is 44/99 like i said its been awhile
i still stick with the limit theorem for this problem
I would think that any calculus teacher would tell you that .49repeting =/= .5 it would probly be one of those limit problems where the number gets infinitely close to .5 but never touches it
that would be the calculus perspective that's the perspective i'll take i guess
that would be the calculus perspective that's the perspective i'll take i guess
ahhh yea that sounds right there is some way to determine the fraction when only one number repeats but i forgot that a few years ago
didn't use one trying to remember ****** from 10th grade does do a whole lot of good for me though
Well, 49/99 is 0.49494949... so if you put the bar over the 49 instead of just the 9, he'd be correct.
Exactly 5 is the only point of vagueness. 0.4999 clearly rounds to 0 because it is still infinitesimally closer to 0. At 5, you could go either way and it's just convention to round up.
ur in the boat with me man i dunno if its cuz i think like a scientist or i don't smoke enough pot but theres no way they gonna see the light

0.4999 does indeed round to 0.
We are talking about 0.4999...... with infinitely many 9's.
Think about this:
1 - 0.9 = 0.1
1 - 0.99 = .01
1 - 0.999 = .001
What happens if you have an infinite number of 9's?
You get an infinite number of 0's.
1 - 0.999999........ = 0.00000000000.......... = 0
Therefore: 1 = .99999..........
In the same way:
0.5 - 0.49 = .01
0.5 - 0.499 = .001
0.5 - 0.4999 = .0001
What happens if you have an infinite number of 9s?
You get an infinite number of 0's.
0.5 - 0.49999........ = 0.0000000000 = 0
Therefore: 0.5 = 0.49999........
again i still think its a limit it never actually is .5 although .4999999..... is infinitely close to .5 it never exactly equals it
last time ill say it for tonight
good-night ATOT
Well, since this is OT and Not HT i'll jsut come out and say it, .4999... rounds to 1, PERIOD. IF you don't understand why then you are either uneducated, stupid, or stubborn.
Might want to check that link in your sig to determine where this post falls in the list of fallacies.

do you agree that 1/3=.3333...? and that 1/3*3=1? Then .33333...*3=.9999999...
n=.9999999
10n=9.99999999
-n -n
9n=9
n=1
that's the way to solve repeating decimals and simplify them to fraction, what you were referring to. Pwned.
You're wrong. I won't go into why because this conversation has been done to death, (including proofs in this thread) but you are wrong. Accept it and learn from it.
now you really don't know much math do you?
to how many significant figures or decimal places do you wanna round it too.

if the answer is 14.49999.... and must be rounded to a whole number, it's rounded to 14.. because no matter what the tenth place and beyond is, you ignore them when rounding to whole numbers, and mathematically speaking.. 14.49999 is closer to 14 than 15, at least as long as you had a calculation device precise enough to see beyond at some point (which will never happen).. hard to explain in words but it should be understood mathematically it drops down since its closer in the most minuscule way possible. no matter how minuscule, it's still closer.
