Understanding the Percentage Formula
The basic percentage formula is: (Part / Whole) * 100 = Percentage. This can be rearranged depending on what you are trying to find.
- To find a percentage:
Percentage = (Value / Total Value) * 100 - To find the part:
Part = (Percentage / 100) * Whole - To find the whole:
Whole = (Part / (Percentage / 100))
