Question 93 (a)

Find a rational number exactly halfway between
$\frac{-1}{3}and\frac{1}{3}$

Answer 1

We know that, a rational number, which is halfway between two rational number i.e. a and b $=\frac{a+b}{2}$
Here $a=-\frac{1}{3}$ and b =$\frac{1}{3}$
$\therefore \frac{a+b}{2}=\frac{-\frac{1}{3}+\frac{1}{3}}{2}=\frac{0}{2}=0$
Hence, the exactly halfway between $-\frac{1}{3}and\frac{1}{3}$ is 0.
