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 please explain.

Answer 1

If the ratio of girls to boys is 3 to 1, then there are 3 parts representing girls and 1 part representing boys.

The total number of parts in the ratio is 3+1 = 4.

Since the total number of students is 400, each part of the ratio represents 400/4 = 100 students.

Therefore, the number of boys is 1 part * 100 students/part = 100 boys.
