Question

The product of two rational rational numbers is -8/9. If on the number is -4/15, find the other?

Answer 1

Answer:

given,

product=-8/9

one of the number =-4/15

let the other rational number be x

so,

-4/15•x=-8/9

x= (-8/9)/(-4/15)

x=-8/9•-15/4

x= 30/9

therefore the other rational number is 30/9

Answer 2

${\huge {\bold{\orange {\underline{Answer:}}}}}$

Let the other number be x

ATQ,

= $\displaystyle\frac {-4}{5}× x =\displaystyle\frac {-8}{9}$

= x =$\displaystyle\frac {-8}{9}÷\displaystyle\frac {-4}{5}$

= x = $\displaystyle\frac {-8}{9}×\displaystyle\frac {-5}{4}$

= x = $\displaystyle\frac {-10}{9}$

$\displaystyle\frac {-10}{9}$ is the required answer of the question.
