Find the midpoint of the two points $A\left(4,\frac{3}{10}\right)\text{ and }B\left(\frac{-9}{10},\frac{-1}{2}\right)$.

**Answer**

$\text{The mid point }M \text{ of any two points } P\left(x_1 ,y_1\right) \text{ and } Q\left(x_2, y_2\right)\text{ is given by }\left(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}\right)$.

$\text{So, the mid point of the given two points is given by:}$

$\left(\frac{4-\frac{9}{10}}{2},\frac{\frac{3}{10}-\frac{1}{2}}{2}\right)=\left(\frac{\frac{31}{10}}{2},\frac{\frac{-1}{5}}{2}\right)=\left(\frac{31}{20},\frac{-1}{10}\right)$
