How to Find the Percentage of a Number: Tips and Tricks for All Types of Learners
Percentages are an essential part of everyday life. Whether we’re calculating tips, discounts or estimating sales figures, knowing how to find percentages accurately can save us time, money and headaches.
In this article, we will cover different ways to find percentages and offer tips and tricks for all types of learners – from those who prefer simple steps to those who love formulas and are already comfortable with the basics.
Simple Steps: Finding the Percentage of a Number
Let’s start with the basics. Finding the percentage of a number can be done quickly and easily using a simple formula:
Percentage * Total Amount = Part of the amount
For example, let’s say you want to find 20% of 50:
20% * 50 = 10
So 20% of 50 is 10. Simple, right?
To make the process even easier you can:
- Convert percentages into decimals, for example, 20% becomes 0.20
- Multiply the decimal and the total amount, and you’ll get the percentage amount.
Using the same example:
0.20 * 50 = 10
The answer is the same. Now you know how to find the percentage of a number quickly and easily.
Using Formulas to Find Percentages
If you prefer formulas, you can use one or more of the following formulas:
- Percent of a number: Percentage * Total Amount = Part of the amount
- Percentage increase: (Change / Original Amount) x 100
- Percentage decrease: ((Original Amount – Change) / Original Amount) x 100
Here are some examples:
Percent of a number:
If you want to find 25% of 80, the formula would be:
0.25 * 80 = 20
So the answer is 20.
Percentage increase:
If the price of a product goes from $20 to $25, then the percentage increase can be calculated as follows:
(5 / 20) x 100 = 25%
The percentage increase is 25%.
Percentage decrease:
If the price of a product goes from $25 to $20, then the percentage decrease can be calculated as follows:
((25 – 20) / 25) x 100 = 20%
The percentage decrease is 20%.
Remember to always double-check your formulas and avoid common mistakes, such as using the wrong formula or forgetting to convert percentages into decimals.
