Understanding Percentages
Definition of Percentage
A percentage is a way of expressing a fraction or a proportion of a whole as a number out of 100. The symbol used to represent percentage is "%". For example, if there are 20 red balls in a bag of 100 balls, the percentage of red balls in the bag would be 20%.
Percentages are commonly used in everyday life, such as calculating discounts, measuring interest rates, and determining the probability of an event occurring. Understanding percentages is an important skill for anyone who needs to work with numbers in their daily life, from students to professionals.
Percentage Calculation Basics
Calculating percentages involves basic arithmetic operations such as addition, subtraction, multiplication, and division. To calculate the percentage of a number, you can use the formula:
percentage = (part / whole) x 100
For example, if there are 25 boys in a class of 40 students, the percentage of boys in the class would be:
percentage = (25 / 40) x 100 = 62.5%
To find what percentage one number is of another number, you can use the formula:
percentage = (part / whole) x 100
For example, if a student scored 75 out of 100 on a test, the percentage score would be:
percentage = (75 / 100) x 100 = 75%
Calculating percentages can also involve finding the part or whole of a number when given the percentage and one of the other values. There are various formulas that can be used to solve these types of problems, including:
- To find the part of a number: part = (percentage / 100) x whole
- To find the whole number: whole = part / (percentage / 100)
Using a percentage calculator like the Percentage Calculator can make these calculations quicker and easier.

Mathematical Concepts
The Formula for Percentage
Percentage is a mathematical concept used to express a proportion or a fraction of a whole as a number out of 100. It is often represented by the symbol "%". The formula for percentage is:
Percentage = (Part / Whole) x 100
In this formula, the "Part" represents the portion of the whole that is being considered, and the "Whole" represents the entire quantity. By multiplying the result by 100, we get the percentage value of the part with respect to the whole.
Examples of Percentage Calculations
Calculating percentages is a common task in many fields, including finance, science, and statistics. Here are some examples of percentage calculations:
Finding what percentage one number is of another: For example, what is 20% of 80? Using the formula above, we get:
Percentage = (Part / Whole) x 100
Percentage = (20 / 80) x 100
Percentage = 25%Therefore, 20 is 25% of 80.
Finding the original value after a percentage increase or decrease: For example, if a product that originally cost $50 is now on sale for 20% off, what is the new price? Using the formula for a percentage decrease, we get:
New Price = Original Price x (1 - Percentage Decrease)
New Price = $50 x (1 - 0.20)
New Price = $40Therefore, the new price is $40.
Finding the percentage change between two values: For example, if a stock price increases from $100 to $120, what is the percentage change? Using the formula for percentage change, we get:
Percentage Change = ((New Value - Old Value) / Old Value) x 100
Percentage Change = (($120 - $100) / $100) x 100
Percentage Change = 20%Therefore, the stock price increased by 20%.

Alternative Methods
There are alternative methods to calculate x percent of y other than using a calculator. These methods can be useful when a calculator is not available or when a quick estimate is needed.
Manual Calculation
One way to manually calculate x percent of y is to convert the percentage to a decimal and then multiply it by y. For example, to find 25% of 80, you would first convert 25% to 0.25 and then multiply it by 80:
0.25 x 80 = 20
Another method is to divide y by 100 and then multiply the result by x. For example, to find 40% of 120, you would divide 120 by 100 and then multiply the result by 40:
120 ÷ 100 = 1.2
1.2 x 40 = 48
Spreadsheet Formulas
Spreadsheets such as Microsoft Excel and Google Sheets have built-in formulas that can be used to calculate x percent of y. The formula for finding x percent of y in Excel is:
