Question

the sum of 2 rational numbers is -7. if one of the numbers is -15/19the other number is?

Answer 1

Answer:

Solution:

A/q:

Sum of the two rational numbers = -7

One of the numbers = -15/9

So,

Other number =  -7 - (-15/9)

                        = -7 + 15/9

                        = (-7×9) + 15 /9

                       = -63 + 15 / 9

                       = -48/9

                       = -16/3

Hence the other number is -16/3.
