Question

como divide 71° 42' 30"

Answer 1

          Deve-se dividir separadamente cada unidade fazendo as conversões 
          necessárias

                        (71° 42' 30") : 7
                    = 71 : 7  42 : 7 30 : 7
                        71 : 7 = 10°
                                     com resto 1°
                                     1° = 60'   acrescentar aos minutos
                                                    42 + 60 = 102
                        102 : 7 = 14'
                                       com resto 4'
                                      1' = 60"
                                      4' = 4 x 60 = 240"
                                                    acrescentar aos segundos
                                                           30 + 240 = 270
                       270 : 7 = 38,57"

                                              (71° 42' 30") : 7 = 10° 14' 38,57"
