We assume that it is 1 because it makes calculations way easier, and the error it creates in reality is so little we can't notice it.
Maybe in the future it will cause problems.
We know .9999... doesn't =1
but in math we say this to cut down the paper work.
There's many other things in math that we assume or bend to our advantage.
so literaly .9999999 doesn't = 1
but for the sake of saving time we say it does.

This is irrelevant, however. How you write a number has no bearing on the number itself. It's the same number whether you write it "1/3" or ".3..." or whatever, just as "3", "three", "tres", and "III" are the same number, regardless of the word, symbol, or notation used to represent it. Any equation written in demical notation could easily be rewritten in fractional notation using roman numerals if you wanted  the validity of the equation has nothing at all whatsoever to do with what notational system you decide to use.
One third times three equals one. There's no magic associated with notational systems that would make this true if you write it one way but false if you write it another. Don't confuse the actual math with the way you write it out. "One third times three equals one" was true long before humans came along and invented writing...

I've been hesitant to reply so far but...
1/3 can be represented by 0.3 repeating. Technically they are not equal. Remember back to 8th grade, 0.3 repeating is found by dividing 1 by 3. If you were to actually do this calculation, you could never could finish.

.9999... (repeating) does euqals to 1. yes, blame math that u can manipulate any ways u want as long as both side equal and ur not breaking the rules.
.9999999 does not equal to 1. do the method below u wont come up with 1 but exactly .9999999.
that one is the correct answer & proof method; learn in calculus about limits.Last edited by The Avatar; 05122007 at 06:25.
