Explicação passo-a-passo:
a/2 = b/3 =c/4= d/5
inverte os denominadores
a/( 1/2) = b/(1/3 ) = c/(1/4) = d /( 1/5 )
achando o mmc de 2,3,4,5 = 60
multiplicando os valores inversos pelo mmc e eliminando ommc
a = 1/2 * 60 = 60/2= 30 >>>>>
b = 1/3 * 60 = 60/3 = 20 >>>>
c = 1/4 * 60 = 60/4 = 15 >>>>
d = 1/5 * 60 = 60/5 = 12 >>>
o exercicio ficou assim resumido >>>>DIVIDIR 3 850 DIRETAMENTE a 30, 20, 15, 12
a/30 = b/20 = c/15 = d/12
aplicando as propriedades a soma na proporção
a/30 = b/20 = c/15 = d/12 =( a + b + c + d )/ ( 30 + 20 +15 + 12 )
a/30 =b/20 = c/15 = d/12 = 3 850/77 ou 50/1
a/30 = 50/1
b/20 = 50/1
c/15 = 50/1
d/12 = 50/1
achando a
a/30= 50/1
a = 30 * 50 =1 500 >>>
achando b
b/20 = 50/1
b = 20 * 50 = 1 000 >>>
achando c
c/15 =50/1
c = 15 * 50 = 750 >>>>>
achando d
d/12 =50/1
d = 12 * 50 = 600 >>>
