conversations.value: I would love to understand how to solve this problem: On national lipstick day, half of the students who attended class wore colored lipstick.  Of those students who wore lipstick, one quarter wore red lipstick.  There were one-fifth as many students wearing blue lipstick as were wearing red lipstick.  If 200 students attended school that day, how many wore blue lipstick?
  Can you explain?

conversations.value: Of 200 students who attended class, half wore colored lipstick, or 200/2=100 students wore colored lipstick.
  Of those students who wore lipstick, one quarter wore red lipstick, or 100/4=25 students wore red lipstick.
  Since there were one-fifth as many students wearing blue lipstick as were wearing red lipstick, then 25/5=5 students wore blue lipstick.
