@TrzyTrypy You can delete the question yourself and that would be the best method to do so.

Added some more explanation. I hope it is more clear now.

@JasonDeVito I guess your objection is invalid, since we are talking about $S$ generating $R$, rather than $S$ being $R$ itself. Since, if $\frac{1}{10} \in S$ then $\frac{k}{10} \in G_{S}$ where $k \in Z$.

@FortuonPaendrag You say that your proof is flawed. I think it would be good if you can probably indicate why do you think it is flawed in the answer itself.

Changed the complete nature of the answer to reflect the comments.

@KevinCarlson Its okay. I do not mind.

comment In what spaces does the Bolzano-Weierstrass theorem hold?
I guess not. So, basically, we want to find conditions for total boundedness and completeness from the metric of the space and the set of points? Is this true?

@KevinCarlson Okay. If I say that total boundedness of a closed subspace of a complete metric space implies compactness and vice-versa. Will that address the question enough?
