The given ratio is 3 girls to 1 boy, which can also be written as 3/1.
In this ratio, there are a total of 3+1 = <<3+1=4>>4 equal parts.
To find the number of boys, we divide the total number of students by the total number of parts and then multiply by the number of parts representing boys.
Number of boys = (Number of students / Total parts) * Number of parts representing boys
= (400 / 4) * 1
= 100 * 1
= <<400/4*1=100>>100
Therefore, there are 100 boys in the school.
The ratio of girls to boys in the school is 3 to 1. If there is a total of 400 students, how many are boys? The answer must be a whole number.
