My full response was in the comments: which in addition to lots of example depending on what type of number was allowed also gave what I thought was the general complex number solution a+bi x 120/(a+bi), a+bi <>0.
Though of course 120/(a+bi) is not expresed in standard complex form which would, I think, be 120a/(a^2+b^2) - 120b/(a^2+b^2)i.
