Question : If you approximate $2.7145$ to $2.715$ then write the percentage relative error.

A) $0.000106$%

B)$0.00106$%

C) $0.0106$%

D) $0.106$%

I tried this by using the following approach : $$100 \times\frac {\text{assumed value }- \text{ original value }} {\text{assumed value }}$$ but I did not get any results. Please anyone help me understand how to solve.

Percent Error =

$ \frac {Vobserved - Vtrue} {Vtrue} = \frac{2.715 - 2.7145} {2.7145} = \frac {0.00049999999999972} { 2.7145} * 100 = 0.018419598452744 % $
