3. In a school, 4 out of every 7 students are girls.
If there are 84 students at the school, how many
are boys?

Answer 1

To find the number of boys in a school where 4 out of every 7 students are girls, multiply 3/7 by the total number of students.

Step-by-step explanation:

To find the number of boys in the school, we need to subtract the number of girls from the total number of students. Since 4 out of every 7 students are girls, 3 out of every 7 students are boys. Therefore, if there are 84 students in total, we can calculate the number of boys by multiplying 3/7 by 84:

Number of boys = (3/7) * 84 = 36

So, there are 36 boys in the school.
