Calculation of the Percentage of Boys in the Class

To calculate the percentage of boys in the class, we need to determine the total number of students in the class before and after the changes.

According to the information provided: - At the beginning of the year, boys constituted 56% of the class, and there were 11 girls. - In the middle of the year, one boy joined the class, and one girl left.

To calculate the total number of students in the class before the changes, we can use the fact that boys constituted 56% of the class. Let's assume the total number of students in the class before the changes is represented by 'x'.

The number of boys in the class before the changes can be calculated as 56% of 'x', which is 0.56x.

The number of girls in the class before the changes is given as 11.

Therefore, the total number of students in the class before the changes can be expressed as the sum of the number of boys and the number of girls:

0.56x + 11 = x

Now, let's solve this equation to find the value of 'x':

0.56x + 11 = x 11 = x - 0.56x 11 = 0.44x x = 11 / 0.44 x ≈ 25

So, there were approximately 25 students in the class before the changes.

After the changes, one boy joined the class and one girl left. Therefore, the new total number of students in
