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 1

Let the number of girls be \(3x\) and the number of boys be \(x\). According to the problem, the total number of students is given as:

\[ 3x + x = 400 \]

Combining the terms gives:

\[ 4x = 400 \]

To find \(x\), divide both sides by 4:

\[ x = \frac{400}{4} = 100 \]

Thus, the number of boys is:

\[ x = 100 \]

Therefore, there are 100 boys in the school.
