How to use location_rel

Hi there, I use appium inspector and seeing ios app element I am interested has a location as {75,185.5} However, when I use location_rel method, I am getting {:x => “0.0 /375.0”, :y =>“0.0 /667.0”}.

Can some one please suggest how I can get the right location for the target object which is {75,185.5}

I am using ruby .

Thank you
