Question

In a class , there are 60% girls. What is the ratio of boys to girls? ​

Answer 1

Answer:

30

Step-by-step explanation:

Correct option is

30

Let the number of boys and girls participating in sports be 3x and 2x respectively.

Then, 3x = 15 or x = 5.

So, number of girls participating in sports = 2x = 10.

Number of students not participating in sports = 60 - (15 + 10) = 35.

Let number of boys not participating in sports be y.

Then, number of girls not participating in sports = (35 -y).

Therefore (35 - y) = y + 5 ⇔⇔ y = 15.

So, number of girls not participating in sports = (35 - 15) = 20.

Hence, total number of girls in the class = (10 + 20) = 30.

Answer 2

Answer:

3:2

Step-by-step explanation:

60%= 60/100

100-60= 40

60:40=3:2(simplest form )
