Question: Phoebe has two pizzas to share with her and three friends. One has pepperoni and the other has cheese. They both have 16 slices. They all eat the same amount. One friend eats only pepperoni, while the rest have an equal number of slices of each. At the end, there is one slice of pepperoni left and 7 slices of cheese, how many slices does each person eat?

[Question]Hannah hangs a 2 foot by 4 foot painting on a 5 foot by 10 foot wall. What percentage of the wall is taken up by the painting?
[Answer]First find the area of the painting: 2 feet * 4 feet = 8 square feet. Then find the area of the wall: 5 feet * 10 feet = 50 square feet.

Q: There are 10 6-ounces of glasses that are only 4/5 full of water. How many ounces of water are needed to fill to the brim all those 10 glasses?
A: A glass is filled with 6 x 4 / 5 = 24 / 5 ounces of water. So, 10 6 - ounces of glasses contains a total of 24 / 5 x 10 = 48 ounces of water. To fill the 10 glasses to the brim, 10 x 6 = 60 ounces of water are needed. Hence, 60 - 48 = 12 ounces of water are still needed. The answer is 12.
