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 whole

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 assume the number of girls is 3x and the number of boys is x.

Therefore, the total number of students is 3x + x = 4x.

Given that the total number of students is 400, we can set up the equation:

4x = 400

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

x = 100

Therefore, the number of boys is x = 100.
