The White Calculator is a useful tool designed to calculate the percentage of a part of a whole. This is especially handy in various fields such as finance, education, and daily life, where you often need to find what portion a part represents of a total amount. This article will explain how the White Calculator works, its formula, and provide a step-by-step example to help you understand its usage better.

## Purpose and Functionality

The primary purpose of the White Calculator is to determine the percentage that a given part is of a whole. This can be particularly useful for tasks such as calculating discounts, grades, statistics, and more. By inputting the part and the whole into the calculator, it performs the necessary mathematical operations to give you the desired percentage.

### Formula

The formula used in the White Calculator to find the percentage is straightforward. It is as follows:

Percentage=(PartWhole)×100\text{Percentage} = \left( \frac{\text{Part}}{\text{Whole}} \right) \times 100Percentage=(WholePart)×100

This means you divide the part by the whole and then multiply the result by 100 to get the percentage.

### Inputs

To use the White Calculator, you need to provide the following inputs:

**Part**: The portion of the whole you are interested in.**Whole**: The total or complete amount.

## Example Calculation

Let’s walk through an example calculation to see how the White Calculator works.

**Example:** Calculate the percentage of 30 out of 200.

**Part**: 30**Whole**: 200

Using the formula:

Percentage=(30200)×100\text{Percentage} = \left( \frac{30}{200} \right) \times 100Percentage=(20030)×100

**Steps:**

- Divide 30 by 200: 30200=0.15\frac{30}{200} = 0.1520030=0.15
- Multiply the result by 100: 0.15×100=150.15 \times 100 = 150.15×100=15

So, 30 is 15% of 200.

## Summary Table

Input | Value |
---|---|

Part | 30 |

Whole | 200 |

Percentage | 15% |

## Conclusion

The White Calculator is a simple yet powerful tool for calculating percentages. By understanding its purpose, functionality, and the formula it uses, you can easily determine what portion a part is of a whole. This can save time and ensure accuracy in various calculations, making it a valuable resource for both personal and professional use.

In summary, the White Calculator helps you:

- Quickly find the percentage of a part relative to a whole.
- Simplify complex calculations with an easy-to-use formula.
- Apply the tool in diverse situations such as budgeting, grading, and statistical analysis.

Using the White Calculator is as simple as inputting the part and the whole, and letting the calculator do the rest. Whether you’re a student, professional, or just someone who needs to perform percentage calculations, the White Calculator is an essential tool to have at your disposal.
