Using the "flip and switch" method, you'd get #-9/5#

Explanation:

Study.com

The opposite reciprocal number is the same as finding the negative reciprocal of a number.

Following the image, we'd replace #a# with #5# and #b# with #9#.

Our first step is to flip #a/b#, or #5/9#. We now have #b/a -> 9/5#.

Our second step is to make our number negative. #b/a -> -b/a#, or #9/5 -> -9/5#.
