Question

The product of two rational numbers is 5/18.
If one of them is
-3/20,
find the other.

​

Answer 1

Answer:

-50/27

Step-by-step explanation:

Product of two rational numbers = 5/18

One number = -3/20

Let the other number be x.

According to Question,

-3/20 * x = 5/18

x = 5/18 ÷ (-3/20)

x = 5/18 * -20/3

x = -50/27

Hence, the other rational number is -50/27.

Answer 2

Answer:

Answer is - 50 / 27

Step-by-step explanation:

The product of two rational numbers is 5 / 18

Let the other number = a

Product number = 5 / 18

= - 3 / 20 × a = 5 / 18

= a= 5/ 18 ~ -3/20

= a = - 5 / 18 × 20 /3

=a = - 50 / 27
