0.999... = 1

no because only 1 can be one no decimal can be 1

hope this helps :)

No this is not technically equal to 1, but for rounding purposes, yes, just round it to 1.

true im sorry for my answer and if it was wrong. anyway have a good day

so 0.999... =/= 1. why is that? 

if it is rounded up to the nearest ones place it will be equal to 1 and so the answer is it will be one if rounded up

Let x = 0.99999....  where there are an infinite number of 9s

10x = 9.99999.....

Subtract x from 10 x:

10x - x = 9.99999..... - 0.999999.....

9x = 9

Divide both sides by 9

x = 1

so  0.99999..... = 1

.

thank you!

what is the mathematical proof of "10 * 0.999... = 9.999..."?

EDIT: how do we know taking finite numbers times infinite numbers is possible? i'm really bad at math
