Question

1).выполни деление с остатком в столбик: 4 567:38, 94 484:47 3 720 :29 2). вычисли : (404*408):2-80070 (567+133)8120-9090

Answer 1

      4.567    :  38                  94.484       :    47                        3720      :   29

      3 8        ----------             94               ------------                  29         -----------

    -----------   0.12               ---------           201                        ---------      128

         76                                 0 48                                             82

         76                                    47                                             58

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

           07                                    14                                           240

                                                                                                  232

                                                                                               -----------

                                                                                                      8

 

2)   ( 404 * 408) : 2 - 80070 = 2 346             ( 567 + 133)

       404 х 408 = 164 832

       164 832 : 2 = 82 416

         82 416 - 80 070 = 2 346
