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!

Find 2 numbers who product is 15 and sum is 16.​
Marizza181 [45]

Answer:

15 and 1

Step-by-step explanation:

x and y are two numbers.

Two equations:

x · y = 15

x + y = 16

Rearrange one of the equations (I'll rearrange the sum equation):

x + y = 16

x = 16 - y

Substitute that to the other equation and solve for y:

x · y = 15

(16 - y) · y = 15

16 - y · y = 15

16 - y² = 15

-y² = 15 - 16

-y² = -1

y² = 1

y = √1

y = 1

Now substitute that to any of the equation and solve for x (in here, I'll choose the multiplication one):

x · y = 15

x · 1 = 15

x = 15

Now verify:

15 · 1 = 15

15 + 1 = 16

This is correct
