Because in this context "0/10" doesn't represent division but rather components of an overall score card. "0/5" and "0/10" are not the same in a scoring sense, because of the fact the outcome is a discrete variable. Keeping the division sign allows viewers to see the potential for error due to truncation and/or rounding of the score to be discrete, and is thus more informative and wholly better judging practice than omitting it.
