Question

Write the additive inverse:

(1) $\frac{5}{9}$
(2) $\frac{-8}{3}$
(3) $\frac{-10}{17}$
(4) $\frac{9}{2}$
(5) −1
(6) 7
(7) −25
(8) 0

Answer 1

If the sum of two rational numbers is 0, then the two rational numbers are said to be additive inverse or negative of each other.
To get the additive inverse, we multiply a number by the negative sign.

(1) $\frac{5}{9}$
The additive inverse of $\frac{5}{9}\mathrm{is}\frac{-5}{9}$ .

(2) $\frac{-8}{3}$
The additive inverse of $\frac{-8}{3}\mathrm{is}\frac{8}{3}$ .

(3) $\frac{-10}{17}$
The additive inverse of$\frac{-10}{17}\mathrm{is}\frac{10}{17}$ .

(4) $\frac{9}{2}$
The additive inverse of $\frac{9}{2}\mathrm{is}\frac{-9}{2}$ .

(5) −1
The additive inverse of −1 is 1 .

(6) 7
The additive inverse of 7 is −7 .

(7) −25
The additive inverse of −25 is 25 .

(8) 0
The additive inverse of 0 is 0 .
