If you want to communicate meaningfully in mathematics, you should reduce ambiguity as much as reasonably possible. Right now, your question is very floppy, and there are many possible meanings one can assign to it. As a result one has to make a big guess to decide on a meaningful answer, and it is socially unacceptable to ask people to make such guesses.

You may be able to leave a small piece vague, and say "I don't know how to make this part precise, but I would appreciate suggestions." If the rest of the question is precise enough to reduce the space of possible meanings to something reasonably small, you might still get a helpful answer.
