Understanding Percentages: A Comprehensive Guide
Calculating percentages can be a confusing and intimidating task, but it’s actually quite simple once you understand the basic principles. In this comprehensive guide, we’ll go over everything you need to know about calculating percentages, including how to find the percentage of a number, how to calculate percentage increase or decrease, and how to solve more advanced percentage problems.
What is a Percentage?
A percentage is a way of expressing a number as a fraction of 100. For example, 50% means 50/100, or one half. Percentages are often used in finance, statistics, and other fields to express how much of something there is.
How to Calculate the Percentage of a Number
To find the percentage of a number, you need to divide the number by the total and then multiply the result by 100. For example, if you want to find out what percentage of 50 is 10, you would divide 10 by 50 and then multiply the result by 100:
(10/50) x 100 = 20%
So, 10 is 20% of 50.
How to Calculate Percentage Increase or Decrease
To calculate the percentage increase or decrease of a number, you need to first find the difference between the original number and the new number. Then, divide that difference by the original number and multiply the result by 100.
For example, let’s say the original number is 100 and the new number is 120. To find the percentage increase, you would do the following:
(120-100)/100 x 100 = 20% increase
To find the percentage decrease, you would do the same calculation but with the new number being the original number and the original number being the new number:
(100-120)/120 x 100 = 16.67% decrease
Advanced Percentage Problems
There are many other types of percentage problems you may encounter, such as finding the original price after a discount or finding the tax on a purchase. To solve these types of problems, you will need to use the same principles outlined above, but with a bit more math.
For example, let’s say you want to find the final price of an item that has a 20% discount. First, you would find the discount amount by multiplying the original price by the discount percentage:
Original price x discount percentage = discount amount
So, for an item that costs $100, the discount amount would be $100 x 20% = $20.
Then, you would subtract the discount amount from the original price to find the final price:
Original price – discount amount = final price
So, for an item that costs $100 with a $20 discount, the final price would be $100 – $20 = $80.
By following these steps and understanding the basic principles of percentages, you can confidently solve any percentage problem that comes your way.
