dogs
1 2 3 4 5 6 7 8 9 0 - , . enter

Explanation:

Step1: Find total parts in ratio

The ratio of birds to dogs is \(3:4\), so total parts \(= 3 + 4 = 7\).

Step2: Find value per part

Total animals are 28, so value per part \(= \frac{28}{7} = 4\).

Step3: Find number of birds

Birds have 3 parts, so number of birds \(= 3\times4 = 12\).

Step4: Find number of dogs

Dogs have 4 parts, so number of dogs \(= 4\times4 = 16\).

Step5: Total animals (verification)

Total animals \(= 12 + 16 = 28\), which matches the given total.

Answer:

Birds: 12, Dogs: 16. Total animals: 28 (already given, but verification confirms).
