A Math Problem.....

ChinaKID · 19th May 2006, 06:13

This problem is just for fun. SO don't flame me.
If u guys are great Hacker. You should be able to explain this math question. Hacker are good at math

Key *=mutiply
0.99recurrence means 0.999999999999 never stop

If 0.99recurrence = 0.33recurrence*3
If 0.33recurrence=1/3
So 0.99recurrence=3*1/3=1
So 0.99recurrence=1

The problem is Our teacher told us 0.33recurrence=1/3
But what happend to 0.99recurrence = 1 ?
If this is correct then text book are wrong. 1/3 does not equal to 0.33recurrence.
3/1 is greater than 0.33recurrence
if u can do it. do it.. if u can't don't force urself.. lol

sorry for bad english.. ^_^

That's what i did.

0.33recurrence
=0.33recurrence/1
=(0.33recurrence*10)/1*10
=3.33recurrence/10
=(3.33recurrence-0.33recurrence)/(10-1)
=3/9
=1/3

Does anyone have any idead about this problem?

I thought 0.99recurrence was LESS than 1? i thoguht it was 0.00recurrence1 less than 1..

if 0.99recurrence = 1, then i think the earth is flat.

Well what did i do wrong...which step? nothing wrong ..but 0.99recurrence= 1?
don't say WTF.......give ur explaination

i can't speak proper english T_Ts rry

.99*3*1/3 = .99 again...

Hey is this MapleStory HAcking section not maths section

set n=0.999......
then 10n=9.999...... (infinite number of 9s, no matter what powers of 10 we multiply by)

therefore, the difference of the 2 equations above gives us
9n=9
n=1
Q.E.D.

Actually, ChinaKID, your right in a sense. You see, math is flawed, mainly because it is made by man.

Not only does your problem show this, (1/3 = 0.333...; 2/3 = 0.666... 3/3 = 0.999..., wait doesn't 3/3 = 1?) but here are some others.

What is x/0 ; x = any number? The answer: undefined. lol (I still think it should equal zero...)

Get a calculator (graphing calc's do this the fastest) and get the square root of a number (any number). Keep getting the square root and you'll eventually end up back at one (1). Make sense? It shouldn't.

But don't worry. Though our current math system isn't exactly perfect, it is all we'll need for a long time and works for the most part.
