Sureley you jest: 1/3 of a yard equals 1 foot, because three feet equals one yard. (Therefore 5 yards equals 15 feet + 1/3rd of a yard which equals 1 foot will equal 16 feet because 15 feet plus one foot equals 16 feet,)

72 inches= 2 yards There are 3 feet in every yard: 3 feet= 1 yard There are 12 inches in every foot: 12 inches= 1 foot Hence: 36 inches equals 1 yard, and 72 inches then equals 2 yards
