99.9m does not equal [.99 (repeated) x 100] so that is not a fair deal.

 

I think it does because:

 

1/9  =  .111111 (repeated)

 

5/9 = .5555555 (repeated)

 

9/9 = .9999999 (repeated)

 

but 9/9 = 1 in fraction form....

 

Thoughts?

You're stupid. how does 9/9 = .99999999.. it equals 1

 

 

I'm stupid? I'm saying it equals both...

I think it does because:

 

1/9  =  .111111 (repeated)

 

5/9 = .5555555 (repeated)

 

9/9 = .9999999 (repeated)

 

but 9/9 = 1 in fraction form....

You are right that it does, but your proof is incorrect. 9/9 can not be .999.. if it also equals 1.

 

Let X = 0.999...

 

Then 10X = 9.999...

 

Subtract X from each side to give us:

 

9X = 9.999... - X

 

but we know that X is 0.999..., so:

 

9X = 9.999... - 0.999...

or:

9X = 9

 

Divide both sides by 9:

 

X = 1

 

X = 0.999... = 1

 

Therefore 0.999... = 1

No it will not. It will just continue getting closer and closer to 1, but will never actually become 1.

Incorrect, you are forgetting that numbers are made up. According to our number system and our math system, 0.999... = 1. View my proof above.

X = 0.999... = 1

 

Therefore 0.999... = 1

 

 

 

 

 

Coming from an engineer major.  99% yield factor gives an ENTIRELY different result as to 100%.  99.99% will ALWAYS give different results to 99.999%, and is usually incomparable to 100%. 
 
For example the PERCENT yield of producing ethanol at yield FACTOR of 100% is over 500% higher than if a yield FACTOR of 99.9999% was used.
 
In some cases that extra decimal makes all of the difference, this is why significant figures is important when working with large numbers. 
 
If you are given a parameter of 99.9999% then it is obviously important to factor in those last 4 decimals, even tho some people claim it can easily be rounded to 1. 
 
If said parameters were given you better use significant figures of 6 for the entire problem or your answer will not be accurate.

Heres another point I feel I should propose:
 
How many numbers are between 1 and 2.  Hence numbers (not full numbers) 
Lets think.. you can do 1.1, 1.2,1.3,1.4, 1.5, 1.6, 1.7, 1.8, 1.9 (so there must be 8 numbers)
No wait what about... 1.01,1.02,1.03,1.05 etc....... (so 98 numbers)
 
Correct answer: infinity!!!!!

The equal marks need to be replaced with approximation marks (~) as they are actually not equal....

 

You will never find in a textbook 1/9=.1111111111  it would actually say 1/9~.111111111 which means it is only a rough estimate...

I figured it out. 
Normally, 
X/9 = .X repeating. yes?

Well

1.3/9 = .1(repeating4)

not = .131313131313

So. Yeah. idk

 

How does 9/9 = .9 repeating? 

 

Just an assumption under the pattern:

 

1/9 = .1 repeating

2/9 = .2 repeating

 

etc.

 

 

 

You cant assume that. That pattern that you are trying to make a relation to is not consistent. Once it gets to 9/9 it is 1, this is elementary...

"this is elementary...."

...........

No need to act superior and complacent on this topic... I created this thread for a fun discussion, not to be confused with a thread for keyboard heroes who are WAY too good at math to be talking with such imbeciles.

This is retarded, just because there is a pattern doesn't mean it is .99999

 

0 + 5 = 5
1 + 4 = 5
2 + 3 = 5
3 + 3 = 5

The answer is 5 because there was a pattern before it hurrr durrrr.

The answer is 9/9 = 1.

Dat logic.............. Please try to make sense next time before you post.

Are you serious? You make the most illogical thread ever written and then say his post is illogical.

I'm very serious. Please explain how my post is "the most illogical thread ever written" (even more illogical, somehow, than this: http://osbot.org/forum/topic/23574-hacked/). Also, if you think a post that says, "3 + 3 = 5 The answer is 5 because there was a pattern before it hurrr durrrr" isn't illogical, then you should get yourself checked out. Seriously.

You proposed a good question dont worry ive heard this argument so many times. Whatd you think of my response?

Very interesting! You make a good point about the usage of "~" rather than "=".
