Question

the product of two rational number is minus 18 upon 75.if one rational number is -9 upon 20 then find the other​

Answer 1

Given:

• The product of two rational number is $\frac{-18}{75}$
• One rational number is   $\frac{-9}{20}$

To Find:

• Find the other​ rational number

Solution:

     Let the other number is $x$

     Product of both numbers $= x \times \frac{{-9}}{20}$

     Product   $= \frac {-18}{75}$

According the question

             $x \times \frac{{-9}}{20} = \frac{-18}{75}$

             $x= (\frac{-18}{75} )(\frac{-20}{9} )$

             $x= (\frac{2}{15} )\times 4$

            $x = \frac{8}{15}$

Thus, The another number is  $x = \frac{8}{15}$

Answer 2

Answer:

The other number is 8/15
