Sorry I don’t know how to answer this question
Additive inverses are numbers that add up to zero, such as 1 and -1.
Z is the additive inverse of -1/9, so z is 1.9.
1.9 + -1.9 =0.
Drag the -1.9 icon to just one mark to the right of -2 on the number line, since each dash equals 0.1.
Drag z to just one mark to the left of 2 on the number line.
The sum will be zero, so drag the sum icon to 0 on the number line.
