<span>To calculate how many pieces that can be cut, we calculate the number of 5 1/2 -inch pieces in 66 inches. To calculate this, we divide 66 by 5 1/2 (i.e. 66 divided by 11/2). 66 divided by 11/2 implies 66 multiplied by 2/11 = 132 / 11 = 12. Therefore, 12 pieces of 5 1/2 - inches pieces can be cut out.</span>
