let's call the animals "a" and birds "b"
b=[latex] \frac{3}{28}a [/latex]
we knot this from3/28 of the animals are birds.
and we also know that 4/15 are birds of prey. so
p=[latex] \frac{4}{15}b [/latex]
we could substitute:
p=[latex] \frac{4*3}{15*28}[/latex]
and solve:
p=[latex] \frac{1}{35}[/latex]
and this is the answer!
