Relative error formula is given as:

`Relative\text{ error = \mid}\frac{Actual\text{ - expected}}{expected}|\text{ }*100\text{ \%}`

`\begin{gathered} Absolute\text{ value of a negative number gives a positive number} \\ \\ Relative\text{ error = 0.00254 }*100\text{ = 0.254} \\ \\ Relative\text{ error = 0.3 \%} \end{gathered}`
