conversations.value: I'm stuck on this math problem: In Dana's senior high school class there were 200 students.  60% of the students were female, and 50% of the females were brunettes.  If 50% of the female brunettes were under 5 feet tall, then how many female brunettes in Dana's high school senior class were under 5 feet tall?
  Can you help?

conversations.value: In Dana's senior class, the 60% of 200 students is 0.6*200=120 female students.
  Fifty percent of the females, or 0.5*120=60 of the female students were brunettes.
  If 50% of the female brunettes were under 5 feet tall, then there were 60*0.5=30 female brunettes under five feet tall in Dana's senior class.
