Word Problem: Sophie and Joan need to determine whether or not they have enough paint to paint the walls of their bedroom. They need 2 6/7 gallons of paint in order to cover the entire room. Sophie has brought 5/6 of a gallon of paint. What is the minimum amount of paint Joan needs to bring in order to paint the entire wall?
Answer: 2 1/42 gallons
Solving Steps:
- 2 6/7 - 5/6 (needs to be simplified)
- 6/7 x 6/6 = 36/42
- 5/6 x 7/7 = 35/42
- 36/42 - 35/42 = 1/42
- 2 + 1/42 = 2 1/42
- Final Answer: 2 1/42 gallons
