The number n and −0.6 are additive inverses. drag and drop −0.6 and n to their correct positions on the number line. drag and drop the label “sum” to the sum of −0.6 and n.

Additive inverse of -0.6 is  negative of -0.6 that is 0.6

Number line is shown in image below.

Step-by-step explanation:

Additive inverse of a number is a number added to that number to get 0 that is thus, negative of the number is the additive inverse.

Here, given p = -0.6

Thus, additive inverse of -0.6 is  negative of -0.6 that is 0.6 .

The correct position of -0.6 and additive inverse  0.6  is marked on the number line shown below.

And the sum of -0.6 and 0.6  is

-0.6 +0.6 = 0

0 is also marked on number line below.

ratio is 2 : 9

the answer is three

13.5 : 3
