Question:
The product of two rational numbers is -14/27. If one of the numbers be 7/9, find the other.
Solution:
Let us assume the other number be y.
Given, product of two rational number = -14/27
One number = 7/9
Then,
= y × (7/9) = -14/27
= y = (-14/27)/ (7/9)
= y = (-14/27) × (9/7)
= y = (-2/3) × (1/1)
= y = -2/3
So, the other number is -2/3
