The definition of 0.(n) is considered to be n/9. Such as 0.(3) = 0.333.. = 3/9 = 1/3. Therefore 0.(9) = 1.

Um, it doesn't? Unless you are talking about rounding, in which case in math this number might round to 1, and you would need to state the rule for the assignment telling what decimal place should be rounded. But, if it is science, then significant digits comes into play and you may need to reference that as well as scientific notation. Then you express the number as an integer multiplied by 10 to the power appropriate to the conversion.
If all this was confusing, it was somewhat intentional. If you are not more specific in your questions, why should we be more specific in our answers?

There is no proof, because technially its not true and can't be proven. However, when dealing with repeating decimals like this, its easier to simply round up for the fact that when calculating with these number the end result is going to be essentially the same -- negligible enough to not be concerned with the precision.

1. Let x = 0.999999...
2. Then 10*x = 9.99999...
3. And 10*x - x = 9.
4. But 10*x - x = 9*x, so 9*x = 9.
5. Thus, x=1, by division.

.99 can be rounded. a frase to help remeber how to round is "5 and above give it a shove, 4 and bellow leave it a lone" since 9 is 5 and above ur round up. but if it was 3.33 you would round down to just 3 because it is 4 or bellow.

it does not. true that each time you add a 9 to the end of that you get closer to 1, but youre taking a smaller step toward 1 each time also. some people like to adjust it to 1 because they like to save time

You take .99 and take the number behind it. If it is bigger than 4 it raise the number to 1.

1/9 = .1111 (continuing)
2/9 = .2222 (continuing)
3/9 = .3333 (continuing)
skip a bit
8/9 =.8888 (continuing)
9/9= .9999 (continuing)
9/9 = 1

Only if you "round up" does it equal '1".
But dealing with absolute values... it doesn't quite make it.

if you start thinking as a mathematician it's not at all,but as an engineer you can round it to 1.
