In a classroom, 1/3 of the students are blonds. If 3/4 of the blonds are girls, what fractional part of the students in the class are blond boys.
Fraction of students who are blonds in the class = 1/3
3/4 of the blonds are girls
The fractional part of students in the class that are blond boys: 1 - 3/4 = 1/4 must be boys.
So the fraction of students that are blond boys is 1/3 x 1/4 = 1/12 .
There are twice as many girls as there are boys in the school's team. If 3/8 of the boys are seniors, they make what fractional part of the classroom.
You want the fractional part of the team that consist of senior boys, so you need to multiply the fraction of boys in the club by the fraction of boys that are seniors.
You know that 3/8 of the boys are seniors, but you aren't told what fraction of the team are boys.
There are twice as many girls as boys. That means that for every 2 girls there is 1 boy, the fraction of boys in the team = 1/(2+1) = 1/3
Therefore the fraction of senior boys = 1/3 x 3/8 = 3/25 - 1/8
