Question

18. The product of two rational
numbers is -3/7. If one of the
numbers is 16/21, find the other.​

Answer 1

Answer:

-9/16

Step-by-step explanation:

Let the unknown rational number be x.

Other rational number = 16/21

Product of them = -3/7

x * 16/21 = -3/7

x = (-3/7) * (21/16)     ----- simplify by cancelling common factors

x = -9/16

Therefore the other rational number is -9/16
