The browser used for posting questions on this site is rubbish. It is quite useless for mathematics since it strips out most symbols so that we cannot tell what the question is meant to be. We could try to guess but in some cases that is not possible and then we may as well make up our own questions and answer them!
In this case we cannot tell whether you intended -4/15 or -41/5, so the answer is not in this case.
