GENTE PFVR É URGENTE, EXPRESSAO NUMERICA COM FRAÇAO
1/4 + 1/3 + 1/2 Isso sobre 1/2+1/2 + 1/3+1/2 + 1/4+1/2

Answer 1

     1/4 + 1/3 + 1/2
   ------------------------------------- =
    1/2+1/2+1/3+1/2=1/4+1/2

Resolvendo o numerador:
      1/4+1/3+1/2 = -----mmc(2,3,4) = 12
      3/12 + 4/12 + 6/12 = 13/12

Resolvendo o denominador":
     1/2+1/2+1/2+1/2+1/3+1/4 =
                           4/2+1/3+1/4 = ----mmc(2.3.4) = 12
                           24/12 + 4/12 + 3/12 = 31/12

Ficou assim:
                      13/12
                     ----------- = 13/12 : 31/12 = 13/12 . 12/31= 13/31
                      31/12
