The number w and 0.8 are additive inverses. drag and drop 0.8 and w to their correct positions on the number line. drag and drop the label “sum” to the sum of 0.8 and w.

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

Therefore, the value of 'w' should be '-0.8' so that .

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.
