Final answer:
To determine the number of boys in a school with 875 students, where 3/5 are girls, multiply the total number of students by 3/5 to find the number of girls (525), then subtract from the total to find the number of boys, resulting in 350 boys.
Step-by-step explanation:
To find out how many boys are in the school when 3/5 of the students are girls, we can first determine the number of girls and then subtract that number from the total student population to find the number of boys.
If there are 875 students and 3/5 are girls, we calculate the number of girls as follows:
Multiply the total number of students by 3/5 to get the number of girls:
875 students × ⅓ = 525 girls.
To find the number of boys, subtract the number of girls from the total number of students:
875 students − 525 girls = 350 boys.
Therefore, there are 350 boys in the school.
