The ratio of girls to boys is 3 to 1. This means that for every 3 girls, there is 1 boy.
Let's say the number of girls is represented by 3x and the number of boys is represented by x.
According to the given information, the total number of students is 400. So, we can write the equation:
3x + x = 400
Combining like terms, we get:
4x = 400
Dividing both sides of the equation by 4, we find:
x = 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. (1 point)
