Dazzla Veteran Share Posted October 1, 2003 x = 0.9999... 10x = 9.9999... 10x - x = 9x 9.9999... - 0.9999... = 9 9 = 9x 1 = x = 0.9999... Link to post Share on other sites

ericnkatz Author Share Posted October 1, 2003 Yeh Thats what im thinking too Dazzla Link to post Share on other sites

Malechai Veteran Share Posted October 1, 2003 x = 0.9999...10x = 9.9999... 10x - x = 9x 9.9999... - 0.9999... = 9 9 = 9x 1 = x = 0.9999... whoa dudes got skills!! Link to post Share on other sites

un4given1 Share Posted October 1, 2003 No. it equals .99999... if you round it then yes. Link to post Share on other sites

OPaul Share Posted October 1, 2003 I say no. .9999... = .9999... 1 = 1 .9999... is a none real number, 1 is a real number. .9999... never reaches 1, it just gets closer and closer indefinitely. Link to post Share on other sites

Bubbo Share Posted October 1, 2003 Another proof that it does equal 1: 0.111... = 1/9 0.111...*9 = 0.999... since 0.111.... = 1/9 -> 1/9 * 9 = 0.999... 1/9 * 9 = 9/9 = 1 Link to post Share on other sites

Dazzla Veteran Share Posted October 1, 2003 Well it's just been proven two times, and disproven zip times. I'd say you've got one up on your mates. Link to post Share on other sites

Samoa Share Posted October 1, 2003 Another proof that it does equal 1:0.111... = 1/9 0.111...*9 = 0.999... since 0.111.... = 1/9 -> 1/9 * 9 = 0.999... 1/9 * 9 = 9/9 = 1 That is incorrect. 1/9 * 9/1 is not the same as 1.... it is .9999.... and cannot equal 1 1/9 = .1111111... .11111... * 9 = .9999999...

Dazzla Veteran Share Posted October 1, 2003 Uhh, you've just posted exactly what he said. You just said: 1/9 = .1111111... 1/9 * 9 = 1 .1111111... * 9 = 0.9999... So you just proved 0.999.... = 1 Congratulations. If Dazzla gives 1 chocolate bar each to 9 kiddies then not only is he weird but they have 1/9 of my stash of sweets, when then give them back I don't have 0.99999.... of a stash, I have one; the beauty of fractions... :p Link to post Share on other sites

Samoa Share Posted October 1, 2003 x = 0.9999...10x = 9.9999... 10x - x = 9x 9.9999... - 0.9999... = 9 9 = 9x 1 = x = 0.9999... if x=.9999 then X cannot equal 1 10x=9.9999 true 10x-x=9x is not true 10(.9999)-.9999=9 9(.9999)=8.991 therefore 9=8.991 is not correct Link to post Share on other sites

un4given1 Share Posted October 1, 2003 so... if what you are saying is correct... .9999999999999999999999...=1 So, if you divide 1 by .9999999999999999999999... then you should get 1 right, because 10/10=1 9/9=1 (here's my proofs) But, infact you get 1.0000000000000000000000000000...1 Thank you Link to post Share on other sites

Dazzla Veteran Share Posted October 1, 2003 10x=9.9999 true (Y) 10x-x=9x is not true (N) LMAO! 10(.9999)-.9999=99(.9999)=8.991 therefore 9=8.991 is not correct Totally misunderstood... Link to post Share on other sites

Dazzla Veteran Share Posted October 1, 2003 so... if what you are saying is correct... .9999999999999999999999...=1So, if you divide 1 by .9999999999999999999999... then you should get 1 right, because 10/10=1 9/9=1 (here's my proofs) But, infact you get 1.0000000000000000000000000000...1 Thank you Hahaha, did you do that on calc.exe?

Please, point out where I said .1111 = 1. 0.9 recurring has been mathematically proven time and time again and is a known fact. Link to post Share on other sites

un4given1 Share Posted October 1, 2003 10x-x=9x is not true where the hell did you go to school? If you subtract something from one side you also have to subtract it from the other side. You can't just make up your own rules. Link to post Share on other sites

Samoa Share Posted October 1, 2003 Dazzla and anyone who believes that .9999 is the same as 1, needs to go back to school or should not have dropped out. I showed your calculations were incorrect, and you laugh cause you think I'm wrong??? Please. Calculators don't lie. Link to post Share on other sites

Dazzla Veteran Share Posted October 1, 2003 OMG, this can't be done on a freaking calcluator because it goes on to infinity you idiot! 0.9 recurring is a rational number, the same way that 0.3 recurring = 1/3. FOOL Link to post Share on other sites

bangbang023 Veteran Share Posted October 1, 2003 x = 0.9999...10x = 9.9999... 10x - x = 9x 9.9999... - 0.9999... = 9 9 = 9x 1 = x = 0.9999... I think you a made a mistake: 10x = 9.9999 but why subtract x then? that doesn't make sense. You would have to divide the X if you want to get it to the other side. Link to post Share on other sites

Samoa Share Posted October 1, 2003 where the hell did you go to school?If you subtract something from one side you also have to subtract it from the other side. You can't just make up your own rules. HELLO LOOK AT DAZZLA'S ORIGINAL FORMULAS, THAT'S WHERE i GOT IT. I WAS DISSPROVING HIS CALUCULATIONS... Did you even go to school? Link to post Share on other sites

Dazzla Veteran Share Posted October 1, 2003 More proof: 0.3 recurring = 1/3 0.3 recurring * 3 = 0.9 recurring 1/3 *3 = 1 0.9 recurring CANNOT be done on a freaking calculator! Link to post Share on other sites

Dazzla Veteran Share Posted October 1, 2003 x = 0.9999...10x = 9.9999... 10x - x = 9x 9.9999... - 0.9999... = 9 9 = 9x 1 = x = 0.9999... I think you a made a mistake: 10x = 9.9999 but why subtract x then? that doesn't make sense. You would have to divide the X if you want to get it to the other side. People, it's not 0.9999, a zero then a decimal place then 4 nines, it goes on to infinity, you CANNOT use a calculator! Link to post Share on other sites

Imperfect63 Share Posted October 1, 2003 oh my, such a simple proof yet so many confused minds... should i show a 1 = 0 proof? :p Link to post Share on other sites

People, it's not 0.9999, a zero then a decimal place then 4 nines, it goes on to infinity, you CANNOT use a calculator! I'm not using a calculator. I am doing the written math. you get 10x = 9.999..... so why are you subtracting X? You don't subtract, you divide by 10 to ge tthe X by itself. if you subract x from one side you must also do it the the other side. Link to post Share on other sites
