Answer:

  1 : 12 : 4

Step-by-step explanation:

Let A, G, C represent the ages of Alex, George, and Carl, respectively. We are told that ...

  A = G +12

  C = 3A . . . . . . . we read this as "3 times as old"; not "3 times older"

  A + G + C = 68

Substituting for G and C, we have ...

  A + (A -12) +(3A) = 68

  5A = 80 . . . . . add 12

  A = 16 . . . . . . . divide by 5

The other ages are then ...

  G = A-12 = 16 -12 = 4

  C = 3A = 3·16 = 48

The ratios are ...

  G : C : A = 4 : 48 : 16

  G : C : A = 1 : 12 : 4
