Question

The product of two numbers is -20/9. If one of the numbers is 4, find the other

Answer 1

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

Answer 2

Answer:

Let the number be x.

x.4=-20/9

x= (-20/9)*(1/4)

x= -5/9
