A veterinarian treated 27 animals in total. What percentage of patients were small animals if he treated 3 ferrets and 4 horses?

To determine the percentage of small animals being treated, we first need to identify the total number of small animals among the patients treated by the veterinarian.

The total number of animals treated is 27, which includes both small and large animals. In the given scenario, the veterinarian treated 3 ferrets (which are considered small animals) and 4 horses (which are considered large animals).

Next, we can calculate the number of large animals treated:

• Total number of large animals (horses) is 4.

From the total of 27 animals, we subtract the number of large animals to find the number of small animals:

• Small animals = Total animals - Large animals = 27 - 4 = 23.

Now that we know the veterinarian treated 23 small animals, we can calculate the percentage of patients that were small animals:

• Percentage of small animals = (Number of small animals / Total number of animals) × 100

• Percentage of small animals = (23 / 27) × 100 ≈ 85.19%.

When rounding this value, we find that approximately 85% of the patients treated were small animals. Therefore, the correct answer is 85%.
