Answer 2

Calculating the Number of Girls in the Class

To calculate the number of girls in the class, we can use the information provided that 2/3 of the total number of students are girls.

Let's denote: - Total number of students as T - Number of girls as G - Number of boys as B

Given that 2/3 of the total number of students are girls, we can express this as an equation: G = (2/3)T

We also know that the number of boys is the remaining 1/3 of the total number of students: B = (1/3)T

Since the total number of students is 30, we can use this information to solve for the number of girls.

Calculating the Number of Girls

Using the equation G = (2/3)T, where T = 30: G = (2/3) * 30 G = 20

So, there are 20 girls in the class.

Therefore, in a class of 30 students, there are 20 girls.
