Question

A piece of wire $\frac{7}{8}m$ long broke into two pieces. One piece was $\frac{1}{4}m$ long. How long is the other piece $?$

Answer 1

Finding the length of the wire:

The total length of the wire$=\frac{7}{8}m$

Length of one piece of wire$=\frac{1}{4}m$

Length of another piece of wire$=$total length of the wire $-$length of one piece of wire

$$\begin{gathered} =\left(\frac{7}{8}-\frac{1}{4}\right)m \\ =\left(\frac{7\times 1-1\times 2}{8}\right)m \\ =\left(\frac{7-2}{8}\right)m \\ =\frac{5}{8}m \end{gathered}$$

$\therefore$Hence, length of the other piece of wire is $\frac{5}{8}m$.
