Calculating the percentage of any number is a straightforward process that can be done with a simple formula. Whether you want to find out what a percentage of a price is or calculate discounts, understanding how percentages work is essential for day-to-day math. Here’s a quick guide on how to calculate the percentage of any number.
1. Understand the Basic Formula
To calculate the percentage of a number, you can use this simple formula:
Percentage of a number = {Percentage/100} x {number}
Where:
– The percentage is the portion of the total number you’re trying to find.
– The number is the whole or total from which you’re calculating the percentage.
2. Example: Find 25% of 200
Let’s say you want to find 25% of 200.
– Step 1: Convert the percentage into a decimal by dividing it by 100. So, 25% becomes 0.25.
– Step 2: Multiply the decimal by the number you are calculating the percentage of (200).
0.25 x 200 = 50
So, 25% of 200 is 50.
3. Example: Find 15% of 80
Now, let’s calculate 15% of 80.
-Step 1: Convert 15% into a decimal: 15 ÷ 100 = 0.15.
– Step 2: Multiply 0.15 by 80.
0.15 x 80 = 12
So, 15% of 80 is 12.
4. Why It Works
Percentages are simply a way of expressing a part of a whole, and multiplying the percentage by the number gives you the desired portion. This formula works for any number and any percentage you want to calculate.
By understanding this simple process, you can quickly calculate percentages for various situations, from shopping discounts to financial calculations.
