Uncertainties query

I was wondering what the uncertainty is in given values e.g. if the question told you the pd was 5.63V, would the uncertainty be +/- 0.005V or +/- 0.01V and why? Similarly, in voltmeters and ammeters, is the uncertainty +/- half of the smallest division or just the smallest division (no halfing)

Thank you very much for any help!
