Painting the House
You have 14-1/2 gallons of paint. You need about 3-1/2 gallons to paint each room of the house. How many rooms can you paint with the paint available?
Represent by picture.
Can paint 4-1/2 rooms (4 rooms with 1/2 gallon left over)
Can paint 4-1/7 rooms (4 rooms with 1/7 room left over)
What are the units of the quotient?
Can paint 4 rooms, because you wouldn't want to start another room without enough paint to finish it.
What assumptions should we make?
Have you used this problem with a class and seen approaches other than(or more specific than) those mentioned above? Or do you have other comments or criticisms or stories? If so, please tell us!
