minus-square@IntriguedIceberg@lemmy.worldlinkfedilinkEnglish18•edit-211 months 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-square@Clinicallydepressedpoochie@lemmy.worldlinkfedilinkEnglish8•edit-211 months 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. It would be better just to have them do the long subtraction If they don’t get it and keep trying to show you how you are wrong they will at least be out of your hair until forever.
minus-square@Laser@feddit.orglinkfedilinkEnglish7•11 months 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-square@Clinicallydepressedpoochie@lemmy.worldlinkfedilinkEnglish4•edit-211 months agoNo, you do subtract from 9.999999…
minus-square@ColeSloth@discuss.tchncs.delinkfedilinkEnglish-11•11 months agoDo that same math, but use .5555… instead of .9999…
minus-square@BeardedGingerWonder@feddit.uklinkfedilinkEnglish8•11 months agoHave you tried it? You get 0.555… which kinda proves the point does it not?
minus-square@Wandering_Uncertainty@lemmy.worldlinkfedilinkEnglish5•11 months 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

No, you do subtract from 9.999999…

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.
