Question

A 10.5 m long wooden stick is cut into three equal pieces. Find the length of the smaller stick. (1 mark)

Answer 1

Solution:
The length of wooden stick = 10.5 m
The wooden stick is cut into three equal pieces.
Thus, the length of the smaller stick can be calculated dividing 10.5 by 3.
$\begin{array}{ccc}10.5÷3& =& \frac{105}{10}÷3\\ & =& \frac{105}{10}\times \frac{1}{3}\\ & =& \frac{35}{10}\\ & =& 3.5\end{array}$
Thus, $\frac{10.5}{3}$ = 3.5
