_________________________________

Let The Rational Number = "x"

Let The Rational Number = "x""x" is multiplied with

$\frac{5}{2} = \frac{5x}{2}$

______________________________

According to the Question Given :-

$\frac{5x}{2} + \frac{2}{3} = - \frac{7}{12}$

$\frac{5x}{2} = - \frac{7}{2} - \frac{2}{3}$

$\frac{5x}{2} = \frac{( - 7 - 8)}{ 12}$

$\frac{5x}{2} = - \frac{15}{12}$

$x = - \frac{15}{12} \times \frac{2}{5}$

$x = - \frac{30}{60}$

$x = - \frac{1}{2}$

Therefore, Required Rational Number =

$= - \frac{1}{2}$
