A. 12
B. 15
C. 18
D. 20

Answer 1

The ratio of cats to dogs is 2:3. By setting up an equation with the total number of animals and solving for the number of cats, we can conclude that out of 30 animals, there are 12 cats.

Step-by-step explanation:

The ratio of cats to dogs is 2:3. In order to find out how many cats there are in a situation with 30 animals altogether, we can follow these steps:

1. Let the number of cats be 2x and the number of dogs be 3x.
2. Since the total number of animals is 30, we have 2x + 3x = 30.
3. Combining like terms gives us 5x = 30.
4. Dividing both sides by 5 to solve for x, we get x = 6.
5. The number of cats is then 2x, which is 2 * 6 = 12.

Therefore, there are 12 cats among the 30 animals.
