Represent each of the following on the number line :

$\dfrac{1}{2}$

Draw a line. Take a point O in the middle. From O, set off equal distances on right as well as on the left. Mark them, as shown. Now, distance OA = 1 unit.

Divide OA into 2 equal parts. Take 1 part out of it to reach the point P.

This point P represents $\dfrac{1}{2}$ on the number line.
