Final answer:
To find the fraction of animals that are birds of prey, multiply the fraction of animals that are birds, 3/28, by the fraction of those birds that are birds of prey, 4/15, giving (3*4)/(28*15) = 12/420. This simplifies to 1/35. Hence, 1/35 of the animals are birds of prey.
Explanation:
The question is asking for the fraction of animals that are birds of prey. From the problem, we are given that 3/28 of the animals are birds and 4/15 of these birds are birds of prey. To find the fraction of animals that are birds of prey, we need to multiply these two fractions: (3/28) * (4/15).
The method of multiplying fractions involves multiplying the numerators together and the denominators together. So, in this case, the numerator would be 3 * 4 and the denominator would be 28 * 15.
Therefore, the fraction of birds that are birds of prey is (3*4)/(28*15) = 12/420. This fraction can be simplified by dividing both the numerator and the denominator by their greatest common factor which is 12, yielding to 1/35. Hence, 1/35 of the animals are birds of prey.
