Answer 2

Given: $\dfrac{2}{3}$ of a class are girls

To find: 1. Ratio girls to boys in the class.

             2. The ratio boys to girls in class

Step-by-step explanation:

Let the Common ratio = x

Number of girls = 2x

Number of students in class = 3x

Therefore

Number of boys in the class= Number of students in the class - number of girls = 3x - 2x = x

So we have

Ratio of girls to boys =   $\dfrac{x}{2x} =\dfrac{1}{2}$

Ratio of boys to girls =  $\dfrac{2x}{x} = 2$

Hence, the ratio of girls to boys is 1:2 and the ratio of boys to girls is 2:1
