Sorry I don't understand the question. r can only exist within the definition of A or B. So we can only view it as something contained in a set.

2, 15/10, 142/100 are in Q but not in B. But they do bound B from above.

please don't repeat this again, it's making you sound like a robot. 😂

How about using the Cauchy sequence approach, I like that one, it looks more understandable.
