Proof of proveit.numbers.division.prod_of_fracs theorem

%proving prod_of_fracs

With these allowed/disallowed theorem/theory presumptions (e.g., to avoid circular dependencies), we begin our proof of
prod_of_fracs:
(see dependencies)

prod_of_fracs may now be readily provable (assuming required theorems are usable).  Simply execute "%qed".
