Answer 2

Calculating the Percentage of Male Students in Class 7

Out of 28 students in the class, 7 are girls. To find out the percentage of male students, we can subtract the number of girls from the total number of students and then calculate the percentage.

Calculation: Total students = 28 Girls = 7 Boys = Total students - Girls = 28 - 7 = 21

Percentage of boys = (Number of boys / Total students) * 100 Percentage of boys = (21 / 28) * 100 = 75%

Therefore, the percentage of male students in the class is 75%.
