A picture 8 3/4 feet long is to be centered on a wall that is 12 1/2 feet long. How much space is there from the edge of the wall to the picture?

Answer 1

12 1/2 = 12.5

8 3/4 = 8.75

12.5 - 8.75 = 3.75 = 3 3/4 feet

divide by two

3.75/2 = 1.875 = 1 7/8 feet

3 3/4 divided by 2 = 1 7/8 feet on each side from the edge of the wall to the picture
