Question: Can you explain how to solve this math problem: Brook Hills High School currently enrolls 3000 students. Half of these students are over 16 years old, and one-fourth of the students over 16 years old are male. The remaining half of the students are under 16 years old, and one-half of the students under 16 are male. In total, how many female students are enrolled at this school?
Answer: 
3000-1500=1500 students are over 16 years old.
1500*0.25=375 students of this age are male.
1500/2=750 students under 16 years of age are male.
In total there are 750+375=1125 male students enrolled.
So, there are 3000-1125=1875 female students enrolled.
