About 224.7 I think. I hope this helps
As we could "drag" these together, we could then do it the easy way.
56
+56
+56
-------
168
------------------------
Or we could also do the following:
56

3:
6

3= 18.
Carry the one.
5

3 = 15+1 (which was carried). = 16
(16+8) =
168
21 * (-1) = -21
21 + (-1) = 20
Answer:
ok so lets find what percentage 630 is of 3050
630/3050=0.20655737704
so about 20.7%
Hope This Helps!!!
