At the Benton Zoo, 1/2 of the animals are primates. Of the primates, 1/2 are monkeys. What fraction of the animals at the Benton Zoo are monkeys?

Write your answer as a fraction or as a whole or mixed number.

Answer 1

To find the fraction of the animals at the Benton Zoo that are monkeys, we can follow these steps:

1. Determine the fraction of animals that are primates: According to the problem, 1/2 of the animals are primates.

2. Determine the fraction of primates that are monkeys: It is given that 1/2 of the primates are monkeys.

3. Calculate the fraction of animals that are monkeys: We can find the fraction of the total animals that are monkeys by multiplying the fraction of animals that are primates (1/2) by the fraction of primates that are monkeys (1/2):

   $$\text{Fraction of animals that are monkeys}=\frac{1}{2}\times \frac{1}{2}=\frac{1\times 1}{2\times 2}=\frac{1}{4}$$

Thus, the fraction of the animals at the Benton Zoo that are monkeys is $\frac{1}{4}$.
