so i know the proof and answer for this but can you try and prove this? don't go and look it up, because that would be cheating.

 

prove that 0.99999999999999999999... = 1

 

go on, give it a shot!

x = .999999.....

 

10x = 9.9999999...

 

10x-x = 9x

 

9.99999.... - .99999... = 9x

9=9x

x=1
