Answer 2

Solution:

Given: The product of two numbers is -8/9
One of the numbers is -4/15.

To Find: the value of other number

Let the other number be x, then (-8/9)x=-4/15
                                                                      x=(-4/15)(9/-8)
                                                                      x=(-4)(9)/(15)(-8)
                                                                      x=(1)(3)/(5)(2)
                                                                      x=3/10..
                    ∴The other number is 3/10
