Hello I need help with understanding a basic math question? A home-decorating company is determining the amount of fabric required for a customer's window treatments. A single window requires 11 2/3 yards and a double window requires 15 5/6 yards of fabric. If there are two single windows and one double window, how much fabric is required?
