Answer 2

Answer:

$- \frac{1}{2}$

Step-by-step explanation:

let rational no. be x

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

$\frac{5x}{2}$

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

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

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

$5x = - \frac{15}{6}$

$x = - \frac{15}{6 \times 5}$

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

hence answer is -1/2
