424/35 * 434/35 = 858/35           512/42 = 256/21

858/35 + 256/21  =    (2574 +1280)/105      3854/105              35   21    3

                                                                                                  35      7    5

 105  / 35 *858 = 2574                                                                7        7   7

  105 / 21 * 256 =  1280                                                              1        1          3*5*7 = 105

424/35 + 434/35 +512/42  el mcm de 35y 42 es 210
[(6*424)+(6*434)+(5*512)]/210
(2544 +2604 + 2560)/210=7708/210 sacamos mitad = 3854/105
