Question

The ratio of boys to girls at a day care center is 2:5. There are 16 boys at the center. What is the total number of boys and girls in the center?


a. 16

b. 40

c. 56

d. 19

Answer 1

The answer is B. 40

You have to multiply 2 times 8 to get 16 so you have to do that to the other side so you multiply 5 times 8 and you get 40.

Answer 2

Answer:

C

Step-by-step explanation:

2 : 5

16:?

So we need to make cross method. So,

5*16: 80

and

2*x: 2x

$\frac{2x}{2}$

$\\ \frac{80}{2}$

So divide both side and we got x:40

Total girls and boys: 56
