Question

In the town zoo 3/28 of the animals are birds of the birds for 4/15 are birds of prey what fraction of the animals at the zoo are birds of prey

Answer 1

4/15 of 3/28....." of " means multiply

4/15 * 3/28 = 12/420 reduces to 1/35 <== birds of prey

Answer 2

`(1)/(35)`

Explanation:

In this problem we have to multiply the fractions, because it says that
`(3)/(28)` of the animals are birds, and from that fraction
`(4)/(15)` are birds of prey. In other words,
`(4)/(15)` of
`(3)/(28)` are birds of the prey. One strategy to solve this quickly is remembering that "of" is translated into math language as multiplication, so:

`(3)/(28) (4)/(15) = (12)/(420) =(1)/(35)`

Therefore,
`(1)/(35)` of the total birds, are birds of the prey.
