@Rapidknight 
Yeah, i do not know what to divide by... any ideas

anonymous · Answer

To have a percentage of something you have to have a portion of a whole
e.g. you scored 40 in a 50 marks test. So the percentage of that would be (40/50)x100=80%
But based on your question, there's no info that suggest anything of the sort.
