The product of two rational number is -14/27 if one of the number is 7/9, find the other

Given

product of two rational numbers = -14/27

One number = 7/9

Find out

We have to determine the other number

Solution

Let us assume the other number be x.

According to given details we get to know that

= x × (7/9) = -14/27

= x = (-14/27)/ (7/9)

= x = (-14/27) × (9/7)

= x = (-2/3) × (1/1)

= x = -2/3

Answer

So, the other number is -2/3
