Answer 2

Answer:

The negative of a rational number is known as its additive inverse. The sum of a rational number and its additive number is equal to 0.

(i) Additive Inverse of 2/8 is

-(2/8) = -2/8

We see that, 2/8 + (-2/8) = 0

(ii) Additive Inverse of -5/9 is

- (-5/9) = 5/9

We see that, -5/9 + 5/9 = 0

(iii) Additive Inverse of -6/-5 is

-(-6/-5) = - (6/5) = - 6/5

We see that, -6/-5 + (-6/5) = 6/5 - 6/5 = 0

(iv) Additive Inverse of 2/-9 is

-(2/-9) = - (-2/9) = 2/9

We see that, 2/-9 + 2/9 = -2/9 + 2/9 = 0

(v) Additive Inverse of 19/-6 is

-(19/-6) = - (-19/6) = 19/6

We see that, 19/-6 + 19/6 = -19/6 + 19/6 = 0
