question about simplify function

This seems like a basic question, but I can't see the answer: Why doesn't either the Simplify or FullSimplify function transform the expression x/(xy) into 1/y? When I substitute a specific value in for x, the simplification occurs as expected, e.g., 4/(4y) transforms to 1/ y. Puzzling. Jack
