In the presented work, we are introduced to the problem of rounding. In the process of numerous human activities, we nd a need, due to various reasons, to divide nite number of objects according to given ratios which cannot be ful lled exactly. Few basic methods have been developed throughout the history, but they were usually designed ad hoc, without appropriate mathematical background. "Fair" method should enjoy several well de ned properties or not allow some undesirable phenomenona. To avoid such paradoxes, restriction to so-called divisor methods is necessary. Within this group, methods should be inspected under additional criteria - mainly the propensity to prefer larger or smaller subjects, bias. Webster's method (Sainte-Lag ue) stands out as the unique unbiased divisor method, also featuring other important qualities. Real data comparison of chosen methods' most important properties is the nal part of this thesis.
