Introduction
Percentage is a concept that is widely used in real-life situations, including financial calculations, statistics, and many other fields. Finding percentages can be daunting for many people, but once you understand the formula, it is straightforward. In this article, we will provide a step-by-step guide and use practical examples to help you understand the concept of finding percentages.
Step-by-Step Guide
The formula for finding the percentage of a number involves three simple steps:
- Divide the percentage by 100 to get a decimal
- Multiply the decimal by the number you want to find the percentage of
- The answer is the percentage of the number
For example, if you want to calculate 25% of 80:
- Divide 25 by 100, which is 0.25
- Multiply 0.25 by 80 which equals 20
- 20 is 25% of 80
Another way to think about this formula is:
Percentage รท 100 x Number = Answer
Visual Aids
Visual aids such as charts and diagrams can be incredibly helpful in understanding percentages. For example, consider the following pie chart showing the percentage of fruits sold in a store:
If you know that the total sales for the day were $1000 and you want to find out how much money was made from selling bananas, you can easily look at the chart to see that 20% of the sales were from bananas. To find out the exact amount, you can use the formula we provided earlier.
Real-Life Examples
Percentages are used in real-life situations such as calculating tax, discounts, and even interest on loans. For example, when calculating the interest on a loan, the percentage rate is multiplied by the amount borrowed to determine the interest payment.
Consider a $5000 loan with an interest rate of 5% per year. The interest for the first year would be 5% of $5000, which is $250. Thus, the borrower would have to pay back the loan amount of $5000 plus the interest of $250, which makes the total repayment amount $5250.
