Theres a matematical equation that can prove that it is the same.

Assuming you mean infinite 3s, yes.

1/3 = 0.333....
2/3 = 0.666....
3/3 = 0.999.....
3/3 = 1

Therefore, 0.9999.... = 1.

this guy is a mathmetician and proves that it is, he also has a lot of cool little "challenges" on his channel, go check it out

doesnt equal to 1. however, .333 that goes on forever times 3 equals to 1. this is because 1/3 times 3 = 1

3x = 1
x = 1/3
x = 0.3...
0.3... * 3 = 0.9...

0.9... = 3x = 1

Unless you're saying that 3 * 0.3... != 0.9...

No, why is this thread back. It doesn't. Nothing in this world is complete. NOTHING.

As a math major, I will put in my 2 cents. .99999999999 is a finite, rational number. .9 repeating, or .9(bar over it) will evaluate to one in most electronic calculations. However, the formal definition of a limit ensures that we can show .9(repeating) does not equal one but does approach it. set .99999 = 1, multiply both sides by 10, then subtract 10 from each side. you do not end up with 0 = 0 therefore it does not equal one.

Ok for all the retarded GD

1/3=.33333

Multiply it by 3.

1=.99999 repeating

0.999... does equal 1
