I'm going to just skip reading all these posts, seeing as how most of you are probably going to make terrible points without explaining yourself very well. .9 repeating = 1, and can be proven with numerous mathematical formulas. However, this statement also breaks many of the fundamental rules of mathematics that you have been taught since grade school. For instance, 1 is a whole number. .9 repeating is a decimal, which is a number that is LESS than a whole number. So how could this be? How can a fraction that is less than a whole number be equal to a whole number? That doesn't make any sense. Secondly, .9 repeating is supposed to be constantly growing, going on into infinity. 1 is not growing in any way. How can this be? This also doesn't make any sense. Logically when looking at it, there is no way that .9 repeating equals 1. However, there are several mathematical proofs that prove it. VERDICT: LOGICALLY: NO MATHEMATICALLY: YES "However it is known to ----- mathematicians that .9 repeating does in fact equal 1." WRONG. This is a heavily debated subject.
well the example is both right and wrong 10x-x = 9 is true since (9.9999... - .99999...)=9 that part is simple and we know that 10x - x = 9x so 9x = 10x-x = 9 in shorthand 9x = 9 x = 1 but at the same time if you take it out of context and do the steps individually 10x - x = 9 but 9x = 8.99991 which is close to 9 just like .999.... is close to 1 but they do not equal each other.
you're using such in a finite manner. .9999999 recurring is infinite. As in there are an infinity of 9s, as in indefinitely long. as in it will never reach that ...81 part. lets do a proof by contradiction. I'm using 1337 photoshop skills for this. http://img153.imageshack.us/img153/892/ohhshiiirj7.png ok I'm making a new(albeit unofficial and unenforced) rule, one with suspension as a punishment. You cannot speak on a math topic unless you've completed highschool algebra with a grade of B or better(or equivillent depending on your circumstances) heck while I'm thinking about it, this thread should be locked...
This is mathematically correct. Since there is 0.99999999999999999999999.... all the way to the end of the universe, it is basically ten. It follows suite to one of the infinite laws: 1/infinite = ZERO
it's not ,999999 it's .9 recurring. there IS a diference. namely the difference between a finite order of magnitude and an infinite order of magnitude.
LOL we should stop referring to the number as 0.999999 and start calling it as 0.999999999999999999999999999999999999999999999999999999999999999999999999999999 99999999999999999999999999999999999999999999999999999999999999999999999999999999 99999999999999999999999999999999999999999999999999999999999999999999999999999999 99999999999999999999999999999999999999999999999999999999999999999999999999999999 99999999999999999999999999999999999999999999999999999999999999999999999999999999 99999999999999999999999999999999999999999999999999999999999999999999999999999999 99999999999999999999999999999999999999999999999999999999999999999999999999999999 99999999999999999999999999999999999999999999999999999999999999999999999999999999 99999999999999999999999999999999999999999999999999999999999999999999999999999999 99999999999999999999999999999999999999999999999999999999999999999999999999999999 99999999999999999999999999999999999999999999999999999999999999999999999999999999 99999999999999999999999999999999999999999999999999999999999999999999999999999999 99999999999999999999999999999999999999999999999999999999999999999999999999999999 99999999999999999999999999999999999999999999999999999999999999999999999999999999 99999999999999999999999999999999999999999999999999999999999999999999999999999999 99999999999999999999999999999999999999999999999999999999999999999999999999999999 99999999999999999999999999999999999999999999999999999999999999999999999999999999 99999999999999999999999999999999999999999999999999999999999999999999999999999999 99999999999999999999999999999999999999999999999999999999999999999999999999999999 99999999999999999999999999999999999999999999999999999999999999999999999999999999 99999999999999999999999999999999999999999999999999999999999999999999999999999999 99999999999999999999999999999999999999999999999999999999999999999999999999999999 99999999999999999999999999999999999999999999999999999999999999999999999999999999 99999999999999999999999999999999999999999999999999999999999999999999999999999999 9999999999999999999999999999999999999999999999999999999999999 More of an effect, see?
try to replace .99(repeat) with .55(repeat) or .22(repeat) or .77(repeat) ect. It works the same way. ex: (all .55 = .55(repeating) .55 x 10 =5.55 5.55 - .55 = 5 5/5 =1/1 read my dam posts, ive posted this same thing 3 times
