Carl is three times older than Alex
The sum of their ages is 68
Find the ratio of George’s age to Carl’s age to Alex’s age.
1:2:5:5:7


1 : 12 : 4

Step-by-step explanation:

Carl = C

George = G

Alex = A

A = 12 + G    ,    G = A - 12

C = 3 * A

C + G + A = 68

Substitute new values for G and C into equation

3 * A + A - 12 + A = 68

5A - 12 = 68

Add 12 to both sides of the equation

5A = 80

A = 16

Alex is 16 years old

Carl is 48 years old

George is 4 years old

4 : 48 : 16

Simplify

2 : 24 : 8

Simplify further

1 : 12 : 4

Hope this helps :)

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.

happy to

pls mark as brainliest.
