10 ----- : 12                             ---------  :  -----------                       

       11                        1                11             1                         1

------------------- * 6 ------ = ----------------------------- * 6 ------------- =

        21                       2                            21                            2

2 ---------                                           2 -------------

        22                                                     11

 

 

       120         1                                                  10

   --------- * --------                                      ---------------

         11         12                     13                        11                              13

          ---------                                                 ---------

              11                                                        11

 

          10                 43            13               10 * 11 * 13

= ------------- : ------------- * ---------- = ------------------------- = сокращаем
