3/28 of the animals are birds. 4/15 are birds of prey. What fraction of the animals are birds of prey.

Verified Answer :

let's call animals "a", and birds "b", birds of prey, "p"

so, b=\(\frac{3}{28} a\)

and p=\(\frac{4}{15} b\)
what;s the relation of p to a?

we substitude b into the last one:

and p=\(\frac{4}{15}* \frac{3}{28} a\)
so:
p=\(\frac{4*3}{15*28} a\)

p=\(\frac{4*1}{5*28} a\)


p=\(\frac{1*1}{5*7} a\)

p=\(\frac{1*1}{35} a\)

which is the answer!
