Sara, either you are being deliberately irksome or you know (next to) nothing about crosswords. With cryptic crosswords, ANYTHING can be a clue, including deliberate misspellings, made up words etc.
The OP has written "11/4", so maybe he means (11, 4) or (11-4) in standard crossword notation...? Unless, of course, "eleven divided by four" is actually part of the clue...
