Mathematics
1 answer:
kipiarov [429]4 years ago

Answer:

Step-by-step explanation:

George: x

Alex: x + 12

Carl: 3(x+12)

3x+36+x+x+12= 68

5x + 48 = 68

5x = 20

x = 4; George's age

4 + 12 =  16; Alex's age

3(4+12)= 3(16)= 48; Carl's age  

George to Alex: 4:16 = 1:4

Alex to Carl: 16:48= 1:3

George to Carl 4:48= 1:12

Carl to Alex: 48:16 = 3:1
