(C) 27 (D) − 3

Answer 1

Answer:

Option(B)

Step-by-step explanation:

Let the two rational numbers be x and y.

Given that x = -4/15.

Product of two rational numbers is -8/9.

⇒ x * y = -8/9

⇒ -4/15 * y = -8/9

⇒ -4y/15 = -8/9

⇒ -36y = -120

⇒ y = 120/36

⇒ y = 10/3.

Therefore, the answer is 10/3.

Hope this helps!
