Answer
Opton A is correct
Step-by-step explanation
The question to be represented on the number line is
1.2 + (-1.6)
Meaning that we first go to the right from 0 to 1.2, then the next part will require us to move towards the left from 1.2; we move 1.6 units towards the left and end up at -0.4
Only Option A shows this.
Hope this Helps!!!
