Answer:

1.6

Explanation:

The way to solve this question is by subtracting the absolute values of the two numbers. |-7.2| - |-2.8|. 7.2 - 2.8 = 4.4. We then need to find the number in the other direction from -2.8 that is 4.4 units away. Since -7.2 is 4.4 units from -2.8 in the negative direction, let's add 4.4 to -2.8 to find the number that is in the other direction. -2.8 + 4.4 = 1.6
