5/8 of a class is girls what is the percentage of boys[ b] if the class has 32 student how many are boys
3/8 = 0.375 = 37.5% are boys.
0.375 * 32 = _______ boys
To find the percentage of boys in the class, we need to first find the number of girls and boys in the class.
Given that 5/8 of the class is girls, we can find the number of girls by multiplying the total number of students (32) by the fraction representing the ratio of girls:
Number of girls = (5/8) * 32 = 20
To find the number of boys, we subtract the number of girls from the total number of students:
Number of boys = Total number of students - Number of girls
= 32 - 20
= 12
To find the percentage of boys, we divide the number of boys by the total number of students and multiply by 100:
Percentage of boys = (Number of boys / Total number of students) * 100
= (12 / 32) * 100
= 37.5%
Therefore, the percentage of boys in the class is 37.5%.
