We show that, for sufficiently large integers m and X, for almost all a =1, ..., m the ratios a/x and the products ax, where |x|≤ X, are very uniformly distributed in the residue ring modulo m. This extends some recent results of Garaev and Karatsuba. We apply this result to show that on average over r and s, ranging over relatively short intervals, the distribution of Kloosterman sums Kr,s(p) = ∑x=1p-1 exp(2 πi (rn + sn-1)/p), for primes p≤ T is in accordance with the Sato--Tate conjecture.
