Menago, I understand.
It really comes down to this.
If we want to use the representation of .(3) = 1/3, then
.(3) + .(3) + .(3) = 1 and not .(9)
It can't be both. In the real world a number can't have two values.
We have to pick the set of rules ahead of time (in this case: .(3) = 1/3), and justify the rules with other rules (in this case, the value of n).
I would cite regulation, but I know you will simply ignore it.
