x=.9999...

10x=9.9999...

Subtract x from both sides

9x=9

x=1

There it is, folks.

Somehow I have the feeling that this is not going to convince people who think that 0.9999... /= 1, but only make them madder.

Personally I like to point to the difference, or rather non-difference, between 0.333... and ⅓, then ask them what multiplying each by 3 is.

[–] BugleFingers@lemmy.world 1 points 1 month ago

The thing is 0.333... And 1/3 represent the same thing. Base 10 struggles to represent the thirds in decimal form. You get other decimal issues like this in other base formats too

(I think, if I remember correctly. Lol)

Cut a banana into thirds and you lose material from cutting it hence .9999

That’s not how fractions and math work though.
