Question

find the answer and prove also​

Answer 1

Let the rational number be x.

A.T.Q -

$-\frac{3}{x}=-\frac{9}{13}\\ \\-9x=-39\\\\x=39/9$

Proof:

$\frac{-3}{\frac{39}{3} } \\\\=\frac{-3*9}{39} \\\\ =\frac{-9}{13}$

Hence, 39/3 must be divided by -3 to yield (-9/13).

Answer 2

Answer:

-3/x=-9/13

=>x=13*(-3)/-9

=13/3

This is the answer.
