    Descompui numerele de mai sus in factori primi si apoi simplifici pana ajungi la forma ireductibila.

        \[\begin{array}{l} \frac{{75*45*35*49*121{\rm{ }}}}{{24*43*55*175*77}} = \frac{{\overbrace {3*{5^2}}^{75}*\overbrace {{3^2}*5}^{45}*\overbrace {5*7}^{35}*{7^2}*{{11}^2}{\rm{ }}}}{{numitor}} = \frac{{{3^3}*{5^4}*{7^3}*{{11}^2}{\rm{ }}}}{{numitor}} = ...\\ \\ {\rm{Fa acelasi lucru si cu numitorul si apoi simplifici!}} \end{array}\]
