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? Answer must be a whole number

Answer 1

If the ratio of girls to boys is 3 to 1, then for every 3 girls, there is 1 boy.

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

The total number of students in the school is the sum of the number of girls and boys: 3x + x = 400.

Combining like terms, we get 4x = 400.

Dividing both sides of the equation by 4, we find x = 100.

Therefore, the number of boys is x = 100.

So, there are 100 boys in the school.
