Explanation:

Convert the mixed number to inches. 3 feet 8 inches = 44 inches (12 inches per foot x 3 feet= 36 inches + 8 inches= 44 inches). 44 inches (length each section needs to be) x 4 (number of sections needed)=176 inches (total molding needed). To determine the amount of molding needed in feet, convert 176 inches into feet by dividing 176 inches by 12 inches. You get 14 2/3 feet, so the shortest board length is 15 feet.

Answer 2

4 sections.....each 3 ft 8 inches

1 ft = 12 inches....so 3 ft = (12 * 3) = 36 inches
36 + 8 = 44 inches...so 3 ft 8 in. is equal to 44 inches

4 sections...each 44 inches.....4 * 44 = 176 inches

176/12 = 14 2/3 ft.....so the carpenter should buy 15 ft <== shortest
