🧾 Formula Behind the Calculation

While the calculator handles the math automatically, here’s the basic formula it uses: Percentage=(PartWhole)×100\text{Percentage} = \left( \frac{\text{Part}}{\text{Whole}} \right) \times 100Percentage=(WholePart​)×100

For example: (25200)×100=12.5%\left( \frac{25}{200} \right) \times 100 = 12.5\%(20025​)×100=12.5%
