What is Percent?
Before we start discussing how to find the percentage of a number, let’s first define what a percent is. Percent is a term used to express a fraction or a proportion in value out of 100. It is usually denoted by the symbol “%”. For example, if someone scores 80% on a test, it means that they answered 80 out of 100 questions correctly.
Why is Finding Percentages Important?
We use percentages in our daily lives more often than we realize. Whenever you see a discount percentage at a store or hear about the percentage of a population vaccinated, you are dealing with percentages. Professions like finance, accounting, and statistics rely heavily on percentages. So, knowing how to find percentages will not only help you in your daily life but also in your career.
How to Find the Percent of a Number: An Overview
There are three methods to find the percentage of a number:
| Method | Formula |
|---|---|
| Percentage Method | Part/Whole x 100% |
| Fraction Method | Fraction x 100% |
| Decimal Method | Decimal x 100% |
In this article, we will discuss all three methods in detail.
Method 1: Percentage Method
Step 1: Identify the Values
The percentage method is used when you know the part and the whole of a value, and you want to find the percentage of the part. For example, let’s say that you got 17 questions right out of 25 on a test, and you want to know your percentage score.
In this case:
- The part = 17 (Number of questions answered correctly)
- The whole = 25 (Total number of questions on the test)
Step 2: Insert the Values into the Formula
The next step is to insert the values into the formula:
Percentage = Part/Whole x 100%
So in our example, the percentage score would be:
17/25 x 100% = 68%
Step 3: Interpret the Result
Finally, interpret the result. In this case, the score is 68%, which means that you answered 68% of the questions correctly.
Method 2: Fraction Method
Step 1: Turn the Fraction into a Decimal
The fraction method is used when you have a fraction, and you want to find the percentage. For example, let’s say that you have the fraction 3/4, and you want to find the percentage.
The first step is to turn the fraction into a decimal:
3/4 = 0.75
Step 2: Multiply by 100%
The next step is to multiply the decimal by 100%:
0.75 x 100% = 75%
Step 3: Interpret the Result
Finally, interpret the result. In this case, 3/4 is equivalent to 75%.
Method 3: Decimal Method
Step 1: Identify the Decimal
The decimal method is used when you have a decimal, and you want to find the percentage. For example, let’s say that you have the decimal 0.35, and you want to find the percentage.
The first step is to identify the decimal:
0.35
Step 2: Multiply by 100%
The next step is to multiply the decimal by 100%:
0.35 x 100% = 35%
Step 3: Interpret the Result
Finally, interpret the result. In this case, 0.35 is equivalent to 35%.
