The illogical mathematics!?- unnecessary knowldge

Hello all!
Right!
It's time to waste your time again...so here we go.

And I think we all know that 1/3 is 0,333333....
And I think we all know that 1/9 is 0,111111...too.
Consequently 9/9 or 3/3 should be 0,999999....
But 9/9 (resp. 3/3) =1/1 because you can shorten with 9 resp. 3...
There the logic of the Mathemathik stops somehow...for me in any case...

I know that one can add to 0,99999... nothing more that it becomes one, but for me this is not 1...but hereby I open the discussion about this topic...so write me your opinion about it in the comments...
Well now that's it again...Cu soon
