Proof of proveit.numbers.division.frac_in_prod theorem

%proving frac_in_prod

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

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