How did you possible get those answers?
You are dealing with the simple metric system, so everything is simply multiplying or dividing by multiples of 10, the significant digits don't change.

1 g = 1000 mg
so (1/100) g = (1/100)(1000) mg = 10 mg

#2
1 mg = (1/1000) g
so .3 mg = (1/1000)(.3) = .0003 g

#3
gr iii /ss= ______mg ----> I haven't got a clue what that means.
