Full description of decays of hadron resonances is applied in these estimations. The predictions of the model at the freeze-out parameters, which were determined independently from measured particle yields and $p_{T}$ spectra, agree qualitatively well with the experimental data. The observed overestimation of the ratio can be explained for more central collisions by the redefinition of $dN_{ch}/dη|_{mid}$.Revtex, 8 figures (included), 11 pages.
