The lower bound on the set of quotients of two subsets $A$, $B$ from finite intervals of natural numbers with positive density is refined. This bound yields an estimate of short distances between the elements of the product of these two sets. In this paper, we borrow problems, approaches, and arguments proposed in [5] of J. Cilleruelo, D. S. Ramana, and O. Ramaré.
Keywords: divisibility, products
Mots-clés : quotients, distances.
