Write the additive inverse (negative) of:

$\dfrac{-4}{-13}$

Write the additive inverse (negative) of:

0

Write the additive inverse (negative) of:

1

Fill in the blanks:

(i) Additive inverse of $\dfrac{-5}{-12}$ = …………… .

(ii) $\dfrac{-5}{-12}$ + its additive inverse = …………… .

(iii) If $\dfrac{a}{b}$ is the additive inverse of $\dfrac{-c}{d}$, then $\dfrac{-c}{d}$ is the additive inverse of …………… .
And, so $\dfrac{a}{b} + \dfrac{-c}{d} = \dfrac{-c}{d} + \dfrac{a}{b}$ = …………… .
