A tiny metallic rectangular sheet has length and breadth of $\displaystyle 5$ mm and $\displaystyle 2.5$ mm , respectively. Using a specially designed screw gauge which has pitch of $\displaystyle 0.75$ mm and $\displaystyle 15$ divisions in the circular scale, you are asked to find the area of the sheet. In this measurement, the maximum fractional error will be $\displaystyle \frac{x}{100}$ where $\displaystyle x$ is $\displaystyle \_\_\_\_$.
