When we say ratio, it is the relationship between two numbers indicating how many times the first number contains the second. In the given ratio above, we can represent it in two other ways. One way is to divide both by 2 and we get 3: 9, and the other way is to divide both by 3, and we get 3: 6. In addition, we can also represent this by dividing both by 6 and we get 1 : 3. Hope this answer helps.
