Doors for the small cabinets are 11.5 inches long. doors for the large cabinets are 2.3 times as long as the doors for the small cabinets. how many large doors can be cut from a board that is 10 feet long?

11.5 * 2.3 = large door size

large door size / 12 = large door size in feet

large door size in feet / 10 = how many large doors can be cut from the board. (you have to round it down if there's a decimal - no 1/2 doors.)
