100% - 20% = 80% на мальчиков и девочек вместе, если бы их количество было равным

Answer 2

Calculating Percentage of Male and Female Students in the Class

To calculate the percentage of male and female students in the class, we can use the following formula:

Percentage = (Number of students of a particular gender / Total number of students) * 100

Given that the number of male students is 20% more than the number of female students, we can represent the number of female students as "x" and the number of male students as "1.2x" (20% more than x).

Calculation

Let's calculate the percentage of male and female students in the class:

Percentage of Male Students: - Number of male students = 1.2x - Total number of students = x + 1.2x = 2.2x - Percentage of male students = (1.2x / 2.2x) * 100 = 54.55%

Percentage of Female Students: - Number of female students = x - Total number of students = x + 1.2x = 2.2x - Percentage of female students = (x / 2.2x) * 100 = 45.45%

Therefore, 54.55% of the students in the class are male, and 45.45% are female.
