A/Q,

➡ x * ( -8/21 ) = 5/9

➡ x = ( 5/9 ) / ( -8/21 )

➡ x = ( 5/9 ) * ( - 21/8 )

➡ ( -105/72 )

➡ ( -35/24 )

➡ Required answer is ( -35/24 )

Answer 2

Heya !!!

This is Your Answer.

It is given that product of two numbers is 5/9.
One of them is -8/21.

Let the other number be y.
So, ATQ
$\frac{-8}{21} \: X \: y = \frac{5}{9} \\ y = \frac{5}{9} \: X \: \frac{21}{-8} \\ y = \frac{-35}{24}$

Hence, the second fraction is -35/24.
