Question

The number w and 0.8 are additive inverses.

Answer 1

This is the correct answer i just did the test

Answer 2

Since, the number w and 0.8 are additive inverses.

A number 'a' is said to have an additive inverse '-a' if "a+ (-a)= 0".

Since, 'w' and '0.8' are additive inverses of each other such that $w + 0.8 = 0$

Therefore, the value of 'w' should be '-0.8' so that $-0.8 + 0.8 = 0$.

So, the value of 'w' is =0.8

Now, Refer to the attached image which represents the position of 0.8 , w ( that is -0.8) and the sum of 0.8 and w.

Sum of 0.8 and w = 0.8 + w

= 0.8 +(-0.8)

= 0.
