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.(1 point)

Answer 1

The ratio of girls to boys is 3 to 1, which means that for every 3 girls, there is 1 boy.

Let's represent the number of girls as 3x and the number of boys as x.

Since the total number of students is 400, we can write the equation as:
3x + x = 400

Combining like terms, we get:
4x = 400

Dividing both sides of the equation by 4, we get:
x = 100

Therefore, there are 100 boys in the school.
