conversations.value: A school principal is booking hotel rooms for a class of 30 students to stay at during an overnight field trip.  Each of the hotel's rooms has two queen size beds, which can fit two students each, and a pull-out couch, which can fit one student.  How many rooms does the principal need to book to fit all of the students in the class?

  Thus, the principal needs to book 30/5 = 6 rooms to fit everyone.
