Answer:
16 * 0.125 = 2
8 * 0.25 = 2
4 * 0.125 = 0.5
0.5 * 8 = 4
So, I tried to figure out what you were saying, but it did not make any sense. You said to find an answer that is the same for all of the problems, but each missing factor was a different number. I researched and solved, but this was the best I could do. I hope this helps in any way!
