A reciprocal is a number that you multiply by so that the result equals 1. The easiest way to find it is to just flip the fraction over.
Here's an example: What is the reciprocal of 3?
3 is the same as 3/1, so we flip and the reciprocal is 1/3
Reciprocal of 4/5 is 5/4
Reciprocal of 2 1/2? Trciky!
Change to a fraction --> 5/2, then flip --> 2/5
