Question

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

Answer 1

$\text{Length of cord} = 71 \frac{1}{2} = \frac{143}{2} \: m$
$\text{It was cut into 11 equal pieces.}\\ \\ \text{Length of each piece} = \frac{143}{2} \div 11 \\ \\ = \frac{143}{2 \times 11} = \frac{13}{2} = 6 \frac{1}{2} \: m$

$\textbf{Length of each piece is 6} \frac{ \textbf{1}}{ \textbf{2}} \: \textbf{m.}$
