Sea:
X = Numero menor
X + 1 = Numero del medio
X + 2 = Numero mayor
X/8 = Octava parte del menor
(X + 1)/3 = Tercera parte del medio
(X + 2)/2 = Mitad del mayor
X/8 + (X + 1)/3 + (X + 2)/2 = X
Hallamos el comun denomidador de 8, 3 y 2
8 3 2 l 2

m.c.m = 2x2x2x3 = 24
(X/8) + (X + 1)/3 + (X + 2)/2 = [3(X) + 8(X + 1) + 12(X + 2)]/24
= [3X + 8X + 8 + 12X + 24]/24
= [23X + 32]/24
[23X + 32]/24 = X
23X + 32 = 24X
32 = 24X - 23X
X = 32
X + 1 = 33
X + 2 = 34
Probemos:
X/8 = 32/8 = 4
(X + 1)/3 = 33/3 = 11
(X + 2)/2 = 34/2 = 17
4 + 11 + 17 = 15 + 17 = 32 Cumple
32 + 33 + 34 = 99
