Understanding percentages is a fundamental skill, whether you're calculating discounts, analyzing statistics, or just trying to figure out a tip. But what if you need to work backward – that is, you know a percentage and a portion of the whole and need to find the original number? Let's explore the methods of how to find the whole number of percentage.

Calculate Whole Number Now! →Understanding the Basics
At its core, a percentage represents a part of a whole, where the whole is considered 100%. When you're given a percentage and its corresponding value, you can use this relationship to determine the original whole number.
The Formula
The fundamental formula we'll use is:
Percentage / 100 = Part / Whole
Where:
- Percentage is the percentage you're working with.
- Part is the value that corresponds to that percentage.
- Whole is the original number you're trying to find.
Finding the Whole Number: Step-by-Step
- Identify the Knowns: Determine the percentage and the corresponding “part” value.
- Rearrange the Formula: To solve for the “Whole,” rearrange the formula:
Whole = (Part / Percentage) * 100
- Plug in the Values: Substitute the known values into the rearranged formula.
- Calculate: Perform the calculation to find the whole number.
Examples
Let's solidify this with a couple of examples:
Example 1: Sales Commission
Suppose you earned a commission of $500, which represents 5% of the total sales you made. What were your total sales?
- Percentage: 5%
- Part: $500
Using the formula:
Whole = (500 / 5) * 100 = $10,000
Therefore, your total sales were $10,000.
Example 2: Test Score
You answered 88 questions correctly on a test, earning you 80% of the total possible points. How many questions were on the test?
- Percentage: 80%
- Part: 88 questions
Applying the formula:
Whole = (88 / 80) * 100 = 110 questions
So, there were 110 questions on the test.
