Question

A cord of length 71 1/2 has been cut into 11 pieces of equal length. What is the length of each piece?

$length \: of \: cord = 71 + \frac{1}{2} cm = \frac{143}{2} cm \\ no. \: of \: pieces = 11 \\ length \: of \: each \: piece = \frac{143}{2} cm \div 11 \\ = \frac{143}{2} \times \frac{1}{11} cm \\ = \frac{13}{2} cm \\ = 6.5 \: cm$
