What is the relative accuracy ratio of an observation taken by a IR(Infrared) sensor which predicts the distance of an object to be 4.16cm but the actual distance is 4.09cm?

What is the relative accuracy ratio of an observation taken by a IR(Infrared) sensor which predicts the distance of an object to be 4.16cm but the actual distance is 4.09cm? Correct Answer 7:409

GiveActual Value=4.09cm Measured Value=4.16cm Absolute error=Measured Value-Actual Value Absolute error=4.16cm-4.09cm=>0.07cm Relative accuracy=(Absolute error/Actual distance) Relative accuracy=(0.07/4.09)=>7:409
