Question

Which of these rational numbers which have additive inverse?

Answer 1

Answer:

The opposite, or additive inverse, of a number is the same distance from 0 on a number line as the original number, but on the other side of 0. Zero is its own additive inverse. In other words, the additive inverse of a rational number is the same number with opposite sign.

Answer 2

Note: the options are missing in the given question, which are as folows:

a. 7

b. $-\frac{5}{7}$  .

c. 0  

d. all of these

Solution:

Understand that, If a number is added to its additive inverse, the sum of both the numbers becomes zero.

Therefore,

• the additive inverse of 7 will be -7.
• the additive inverse of $-\frac{5}{7}$   is $\frac{5}{7}$ .
• the additive inverse of 0 is 0.

Hence, the correct answer is option d. i.e., all of these.
