Answer:
The ratio between men and children is 4:3.
Explanation:
Since in a ferry, the ratio of the number of woman to the number of man is 3: 2 and the ratio of the number of woman to the number of children is 2: 1, to find the ratio of the number of man to the number of woman to the number of children in the ferry, the following calculation must be performed:
3 women for every 2 men = 6 women for every 4 men (x 2)
2 women for every 1 child = 6 women for every 3 children (x 3)
6 women + 4 men + 3 children = 6: 4: 3
Thus, the ratio between men and children is 4:3.
