Explanation:
Let Carol's age be represented by "C" and Mary's age by "M".
According to the problem, we know that:
1/3 C = 2M
To solve for C, we can multiply both sides of the equation by 3:
C = 6M
Now we can find the ratio of Carol's age to Mary's age:
C/M = 6M/M = 6
Therefore, the ratio of Carol's age to Mary's age is 6:1
