Question

Write the additive inverse of 21/31

Answer 1

Step-by-step explanation:

additive inverse of 21/31=-21/31

as 21/31+(-21/31)=0

Answer 2

Answer:

$\frac{-21}{31}$ is the additive inverse of $\frac{21}{31}$.

Step-by-step explanation:

Explanation:

Additive inverse:A number's additive inverse is the value that, when added to the original number, yields a value of zero. It is what we add to a number to make it equal to zero.

If "a" is the starting number, then its additive inverse will be "a's" negative value, or "-a," such that "a+(-a)" = "a - a" = 0.

Now according to the property of additive inverse,

⇒$\frac{21}{31} + \frac{-21}{31}$ = 0

Therefore, additive inverse of $\frac{21}{31}$  is $\frac{-21}{31}$.

Final answer:

Hence, $\frac{-21}{31}$ is the  additive inverse of$\frac{21}{31}$.
