**The Basics of Calculating Percentages
At its core, a percentage is a way to express a portion or fraction of a whole, represented as a value out of 100. The symbol "%" is used to denote percentages. To calculate a percentage, one needs to divide a specific value by the total and then multiply the result by 100.
The formula for calculating a percentage is as follows:
```
Percentage = (Part / Total) * 100
```
Where "Part" is the value of interest, and "Total" is the overall quantity.
