Question

A wire of length $12\frac{1}{2}\mathrm{m}$ is cut into 10 pieces of equal length. Find the length of each piece.

Answer 1

$$\begin{gathered} 12\frac{1}{2}\mathrm{m}=\frac{(12\times 2)+1}{2}\mathrm{m} \\ =\frac{25}{2}\mathrm{m} \end{gathered}$$

Length of one piece = $\frac{\mathrm{Length}\mathrm{of}wire}{10}=\frac{25}{2}\times \frac{1}{10}=\frac{25}{20}$
Length of one piece = $\frac{\cancel{{25}^5}}{{\cancel{20}}^4}=\frac{5}{4}\mathrm{m}$
