Subject: [PATCH 3/3] Replace non-descriptive parameter names with descriptive
 ones

Changed parameter names from 'a' and 'b' to 'numerator' and 'denominator' throughout the function to satisfy the 'require descriptive names' requirement from algorithms-keeper bot. Updated function signature, docstring, and all usages within the function body.
