$let \: us \: take \: the \: first \: rational \: number \: \\ be \: x \: and \: second \: one \: be \: y$

$acco \: to \: question \\ = > x = \frac{14}{2} \\ and \\ = > x \times y = - \frac{28}{75} \\ = > \frac{14}{2} \times y = - \frac{28}{75} \\ = > y = - \frac{28}{75} \times \frac{2}{14} \\ = > y = - \frac{4}{75} \\ so \: second \: number \: will \: be \: - \frac{4}{75}$

Answer 2

Answer:

Hey dear!!

Given,

Sum of two rational nos. = -7

One no. is -5/2

Now,

Suppose the other no. be x

-5/2 + x = -7

x = -7 + 5/2

x = -14+5/2

x = -9/2

Therefore, the other no. is -9/2.

Hope it hlpz...
