There are 22 boys and 18 girls in class 53. The number of men and women accounts for several percent of the class

The number of boys △ the number of students in the class = the number of boys in the class
The number of female students △ the number of students in the class = the number of female students in the class
Therefore, the number of students in the class = female + male = 22 + 18 = 40
So boys account for a few parts of the class = 22 △ 40 = 11 / 20
What is the percentage of female students in the class = 18 △ 40 = 9 / 20
