# Thread: Can some math genius help me out?

1. ## Can some math genius help me out?

OK, something just occurred to me. If I have 3 equal parts of something which are all part of one whole, according the 100% standard we have, If I were to separate them, they should grow exponentially. If I use 1/3 1/3 is .3333333. . . So how does one divide by 3s when it comes to percentages and math?

Your wrong. basically you have a 3rd of a 3rd of a 3rd....... its like the 1/2 paradox. if i walk hald the distance between you and me forever i will never actually reach you because you can keep dividing by 1/2's

Mathematically, one would have to be bigger than the others or the sum of all three would have to be bigger than the whole. Yet, that is not happening.

You just cant divide something equally into 3 pieces.

Quoting you this time, so it doesn't change. I can split 100 in half. 50 / 50 ok, but I can't split it into thirds.

Percentages (and arithmetic in general) are abstractions. Sometimes difficulties arise in achieving precision when relating the abstractions to the reality. I suspect that the OP's question relates to the limitations of the representation of an abstraction.

I just devided something into 3 equal pieces.

1) - 2) - 3) - <all the same length>

i misunderstood your question so i edited it but my first post of round up applies.

100/3 = 33.3333333333going on forever
its an irrational number because it never ends. thus can never become a whole 100% because you cant add an irrational number to anything to equal a whole.

So is there a way to make up for that in Mathmatics?

10. ## Re: Can some math genious help me out?

Make up for it how? You can either use a lot of decimal points or stick to fractions. I mean, you've heard about the game of calculating pi, right?

Three isn't special, though. If you started with 99, that's divisible by three but not by two. The fact that .333333 looks like it has a three in it doesn't make it an integer. = )
