The answer is B. If you multiply it you get the original problem.
72 inches.
<span>72/6=12inch sixths </span>
<span>each sixth is cut into a third </span>
<span>12/3=4 inches </span>
<span>each of these eighteenths (6*3=18) have a length of four inches. </span>
<span>Check. 18*4 should equal 72. You have 18 pieces, each four inches long.
Got it all?</span>
