Cam has a piece of plywood that is 6 7/8 feet wide. He is going to cut shelves from the plywood that are each 1 1/6 feet wide. Which is a good estimate for the number of shelves Cam can make?
6 7/8= 55/8 6 1/6= 7/6 first find common denominators 55/8 * 3= 165/24 7/6 * 4= 28/24 165/24 divided by 28/24 is the same as 165/24 time 24/28 so that equals 3960/672 which equals 5.8928 so estimates about 5 shelves
