Question: A 25 story building has 4 apartments on each floor. If each apartment houses two people, how many people does the building house? Think carefully first, then make a decision:
If each building floor has 4 apartments, we have 25 floors * 4 apartments / floor = 100 apartments. If each apartment has 2 people, 100 apartments * 2 people / apartment = 200 people. So the answer is 200.
