Answer 2

Hey friend, Harish  here.

Here is your answer:

Given that,

Product of two rational  numbers is  --- $\frac{-4}{9}$


One number is ----      $\frac{-2}{27}$

To find,

The other number.

Solution,

Let the unknown number e ' x ' 

Then, 

$\frac{-2}{27} \times x = \frac{-4}{9}$

⇒  $x = \frac{-4}{9} \times \frac{-27}{2}$

Now,  simplify.

⇒  $x = 2\times 3 = 6.$

Therefore the another number is 6.
