Mason plans to repaint some classroom bookcases. He has 5 5/7 gallons of paint. All of the bookcases are the same size and each require 1/2 gallon of paint. How many bookcases will the custodian be able to repaint with that amount of paint?

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.

B. 2 1/2 feet. multiply 2.5 inches by 12 to get thirty inches then divide by 12 to get 2.5 feet
