Answer

Let the required number be 'X'

Condition 1 :

$\frac{X}{X} = 2 X = > 2 X^{2} = X = > X = \frac{1}{2}$

Condition 2 :

$X \times X = \frac{X}{2} = > X = \frac{1}{2}$

Therefore, $(\frac{1}{2})$ is the number which becomes double when it is divided by itself and becomes half when it is multiplied by itself.
