Lets call X the number of girls and since the boys are three times the number of girls, we will call them 3x. The total number of students is 116.
Lets create an equation to find out the number of boys and girls. A class is formed from the number of boys and the number of girls. So:
x+3x=116
4x=116
Divide both sides with 4.
4x/4 = 116/4
x=29 girls
3x= 29*3
3x = 87 boys
