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

C

Explanation:

2 : 5

16:?

So we need to make cross method. So,

5*16: 80

and

2*x: 2x

`(2x)/(2)`

`\\ (80)/(2)`

So divide both side and we got x:40

Total girls and boys: 56

Answer 2

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.
