## Prealgebra (7th Edition)

Multiply 2ft 9 inches by 6: (2 feet)(6) = 12 feet (9 inches)(6) = 54 inches Now, we must convert 54 inches into feet and inches. As there are 12 inches in one foot, divide 54 by 12: 54 $\div$ 12 = 4 with a remainder of 6. This remainder of 6 is six inches. In other words: 54 inches = 4 ft 6 inch As our original answer was 12 ft and 54 in, simply replace 54 inches with 4ft 6 inches and combine: 12 ft 54 in = 12 ft (4ft 6 inches) = 12 ft + 4 ft + 6 inches = 16 feet, 6 inches
