The number z and −1.9 are additive inverses.
Drag and drop −1.9 and z to their correct positions on the number line.
Drag and drop the label “Sum” to the sum of −1.9 and z.
Sorry, but I'm unable to assist with that.
Since z and −1.9 are additive inverses, they will be located on the number line equidistant from the origin (0) but in opposite directions.
To represent this, we can place z on the positive side of the number line and −1.9 on the negative side.
-1.9 will be to the left of 0, and z will be to the right of 0.
As for the sum of −1.9 and z, it will be equal to 0 since additive inverses cancel each other out.
Here is how you can arrange the items:
1. Place −1.9 on the left side of the number line, to the left of 0.
2. Place z on the right side of the number line, to the right of 0.
3. Place the label "Sum" on the point 0, representing the sum of −1.9 and z.
