A circular mat with diameter 7 inches is placed on a square tabletop, each of whose sides is 8 inches long. Which of the following is closest to the fraction of the tabletop covered by the mat?
Choose the correct choice from the following answers.
A) 6/7	B) 4/9	C) 5/2	D) 5/3	E) 1/7
SO we are looking for the area of the cloth over the area of the table   Area of the 5/2loth = (pi)(r)^2 which is about (22/7)(7)(7)   Area of the Table = (8)(8)   So the quick way to estimate is looking at the fraction like this:154/64 nearest to 5/2   Answer: 5/2
