So if you're adding two negatives you move left, positive you move right, and when you have to determine a negative, and a positive you just have to see which one is the farthest from zero which the farthest one's sign is either positive, or negative. Positive to move right, and negative to move left.

Answer:
<h2><em><u>
11.2 - B to C</u></em></h2><h2><em><u>
12 - B to A</u></em></h2><h2><em><u>
8.8 - A to C</u></em></h2>
You have to multiply all the sides by 4.
B to C = 2.8*4
2.8 * 4 = 11.2
B to A = 3*4
3*4 = 12
A to C = 2.2*4
2.2*4 = 8.8
Hope this helped!
