Final answer:

To find the number of adult cats when the ratio of adult cats to kittens is 5:4 and there are 20 kittens, we set up a proportion. We calculate 5 times the number of groups of kittens (5 groups), which gives us 25 adult cats.

Step-by-step explanation:

The question asks us to find the number of adult cats based on a given ratio and the number of kittens. The ratio of adult cats to kittens is 5:4. If there are 20 kittens, we can set up a proportion to find the number of adult cats. For every 4 kittens, there are 5 adults. So if there are 20 kittens (5 groups of 4), we will have 5 groups of adult cats as well.

To find the number of adult cats, we calculate 5 times the number of groups of kittens, which is:
5 × 5 = 25. Therefore, there are 25 adult cats. The correct answer is a) 25.
