convert a newman projection to a fisher projection

[anteater85]

Hi guys,
I was doing the Kaplan Ochem test and I came to a question.

I know how to go from newman to fisher but the thing that makes me confuse is where each atom goes.
for example for doing R and S. how do u know which atoms are in front and which ones are in the back?

staggered conformation doesn't have correct orientation of bonds for Fisher projection, so transform molecule to eclipsed form in order to construct Fisher projection. give me the question, i'll try to answer it
