Question

By what rational number should -3 is divided to get -9/13?​

Answer 1

let, the required rational number be x

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

By taking reciprocal to both the sides,

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

$x = (\frac{13}{ - 9}) \times ( - 3)$

$x = \frac{13}{ 3}$

So, the required rational number is

$\frac{13}{3}$
