So 1 can be divded into 3 1/3ths, which are supposedly equal and make a whole 1, but when you do that with decimals you get 3 of 33.33333333333333333(goes on forever) which when added still leaves you with a 0.00000000000000001. Are fractions wrong or or decimals wrong or is our 21st centry math wrong? Ever since 2nd grade i ask people this and I never get a straight answer, it's almost like nobody cares. Are you guys gonna explain this to me?

None of the above. Take either a course on real analysis or mathematical logic. Learn the definitions of "convergent sequence", "Cauchy sequence", "rational number", and "real number".

Your problem is that you don't really understand what "goes on forever" means. You seem to think it means "goes on for a long time then stops". No, it NEVER stops. It goes forever. There is no leftover 0.00001, or leftover .00000001, or leftover 0.000...01 no matter how far out you go.

But mathematically you cannot deny that it's there. The 1 is never made whole.

Youre either a troll or you don't understand what the person you responded to said. There is not 1 at the end of that sequence, because there is no end of that sequence. No 0.000...01. It does not exist.

0.33333333... goes on continuously.

So that proves that I'm right. If the 0.1 is never created then the 1 is never a whole from 3 equal parts.

It's an awful joke but at the same time you put 33.333 rather than 0.3333 so I have no idea..

Yeah basically it's just a representation of a value or quantifying system.. one of many systems.

It is an answer. At first I thpugh you were genuinely interested in an answer. Now I just think you're a shitty troll. The answer is pretty obvious provided (1) you know how to read and write proofs, (2) you know about the concept of convergence/how epsilons and deltas are used, and (3) you know that real numbers are defined as equivalence classes of Cauchy sequence that converge to the same limit. If you understand those three things, then the answer to your question is trivial.

1/3= 0.333...
1/3 * 3 = 0.333... * 3
1 = 0.999...

Now, you might think this means you need a ...1 at the end added to get it up to 1, but that is not the case. Actually 0.999... is exactly identical to 1. It's not less. If you want to understand, try to think of the EXACT placement where you would need to add a 1 to make it equal to 1. No matter how far you went down the fractions, you would still need to go farther. It's endless. If you still don't get it try googling "does .999 equal 1", there are countless proofs out there in various methods

0.99999999999999 and 1 are not the same. They are physically not the same number. You can approximate but that's avoiding the issue here. Can you show me a "proof"? Why can't you just prove it right here?

Yes, it can be replace with anything, because anything divided by itself is 1.

5/5 = 1.
8/8 = 1.
0.5/0.5 = 1.
1/0.999999...... = 1.

Why? because 1 and 0.999... are the same number.

Ok how about this: think of a number line where one isn't just a thing but also a place. Now think of 1 and 0.9999 repeating not just as symbols for numbers but also as directions.
The instructions take one step takes you to one
The instructions take
nine tenths of a step then
nine hundredths of a step then
nine thousandths of a step then
nine ten thousandths of a step
On and on and on take you to the same place as taking one step.

If the directions/symbols take you to the same place on the number line then they represent the same number, all be it in different ways.

Yes, in a sense. The minus sign defines a direction of approach. The repeating decimal notation does not.

Other than that you are correct. Try it with 1/3 and 0.33333. You can approach from either the positive or negative side of the number line but you will still arrive in the same place.

Oh ok. Yeah if you don't know about convergence or how real numbers are defined then that's why this doesn't make sense. They will probably be fairly difficult concepts to grasp at first, but the key point is uderstanding convergence and the definition of real numbers. You have probably already learned about convergence in a calculus class. As for the definition of real numbers, the idea that they're "equivalence classes of Cauchy sequences rationals" probably sounds like meaningless jargon, but it makes perfect sense after you familiarize yourself with the terminology. Its basically saying that a real number like 3.14159... (pi) can be approximated by a sum 3 + (1/10) + (4/100) + (1/1000) + ... and that the more terms you add to the sum, the more accurate it becomes.
