3/5 of the class were boys. The teacher divided the boys equally into groups so the each group of boys had 1/10 of the number of
students in the class. The teacher then divided the girls equally into groups such that each group of girls had 1/5 of the number of students in the class? How do I do this and what's the answer?
I think boys =18 girls=12 boys :x girls:y student:z the number of group for the boys :n the numberof group for the girls :m so x=(3/5)*z y=(2/5)* z x/y=3/2 3y-2x=0 (1/10)*z*n=(3/5) *z so n=6 (1/5)*z*m=(2/5)* z put x=(1/10)*z*6 y=(1/5)*z*2 into 3y-2x=0 and z=30 z=30 so x=(1/10)*30*6=18 y=(1/5)*30*2=12
