conversations.value: I'm completely lost with this math problem: Of the 600 students at River Falls High School, 3/4 of them play tennis. Of those that play tennis, 60% of them also play hockey. How many students play both hockey and tennis?
  Can you give me a hand?

conversations.value: 3/4 of the students at River Falls High School play tennis, a total of 3/4*600=450 students
  Of those that play tennis, 60% of them also play hockey, meaning 60/100*450=270 students play hockey and tennis.
