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

vova2212 [387]

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!

3(4x^2y^3 + 2x^3) – 4(9x^3y^2 – 6x^2y^3)<br> How to solve pls?

babunello [35]

Answer:

$3(4 {x}^{2} {y}^{3} + 2 {x}^{3}) - 4(9 {x}^{3} {y}^{2} - 6 {x}^{2} {y}^{3} ) \\ = (12 {x}^{2} {y}^{3} + 6 {x}^{3} ) - (36{x}^{3} {y}^{2} - 24{x}^{2} {y}^{3}) \\ = (12 {x}^{2} {y}^{3} + 6 {x}^{3} ) + ( - 36{x}^{3} {y}^{2} + 24{x}^{2} {y}^{3}) \\ = - 36{x}^{3} {y}^{2} + 36x^{2} {y}^{3} + 6 {x}^{3}$

I hope I helped you^_^
