minus-squareIntriguedIceberg@lemmy.worldlinkfedilinkEnglisharrow-up0·edit-21 year agoIt still equals 1, you can prove it without using fractions: x = 0.999… 10x = 9.999… 10x = 9 + 0.999… 10x = 9 + x 9x = 9 x = 1 There’s even a Wikipedia page on the subject
minus-squareClinicallydepressedpoochie@lemmy.worldlinkfedilinkEnglisharrow-up0·edit-21 year agoI hate this because you have to subtract .99999… from 10. Which is just the same as saying 10 - .99999… = 9 Which is the whole controversy but you made it complicated.
minus-squareLaser@feddit.orglinkfedilinkEnglisharrow-up0·1 year agoYou don’t subtract from 10, but from 10x0.999… I mean your statement is also true but it just proves the point further.
minus-squareClinicallydepressedpoochie@lemmy.worldlinkfedilinkEnglisharrow-up0·edit-21 year agoNo, you do subtract from 9.999999…
minus-squareColeSloth@discuss.tchncs.delinkfedilinkEnglisharrow-up0·1 year agoDo that same math, but use .5555… instead of .9999…
minus-squareBeardedGingerWonder@feddit.uklinkfedilinkEnglisharrow-up0·1 year agoHave you tried it? You get 0.555… which kinda proves the point does it not?
minus-squareWandering_Uncertainty@lemmy.worldlinkfedilinkEnglisharrow-up0·1 year ago??? Not sure what you’re aiming for. It proves that the setup works, I suppose. x = 0.555… 10x = 5.555… 10x = 5 + 0.555… 10x = 5+x 9x = 5 x = 5/9 5/9 = 0.555… So it shows that this approach will indeed provide a result for x that matches what x is supposed to be. Hopefully it helped?
It still equals 1, you can prove it without using fractions:
x = 0.999…
10x = 9.999…
10x = 9 + 0.999…
10x = 9 + x
9x = 9
x = 1

x = 0.555…
10x = 5.555…
10x = 5 + 0.555…
10x = 5+x
9x = 5
x = 5/9
5/9 = 0.555…
So it shows that this approach will indeed provide a result for x that matches what x is supposed to be.
