observation

This question was also very popular among the candidates.  However, there was a need to emphasize that number bases are non-negative.  Some candidates did not state so.  Also, some candidates had problems with the (b) part as they did not realize that they had to clear the fraction first.

Generally, the performance was satisfactory.
