jessie is building a dog house . For one side of the roof ,she needs a board that is 7 3/4 feet long. she has a board that measures 9 1/12 feet. how much of the length does she need to cut from the board?
 
Try converting the fractions so they have the same denominator. First find the lowest common denominator.
