What is a Percentage?
Before we delve into the steps to find percentages, let’s first define what a percentage is. A percentage is a fraction of 100. When we want to express a part of a whole as a percentage, we multiply the decimal or fraction by 100. For instance, 0.75 is equivalent to 75%, and 2/5 is equivalent to 40%.
The Importance of Percentages
Percentages are used in various fields, including finance, science, and business. In finance, percentages are used to calculate interest rates, returns, and taxes. In science, percentages are used to express concentrations, amounts, and changes. In business, percentages are used to determine profit margins, discounts, and growth rates.
The Steps to Find Percentage
Now that you understand what a percentage is and its importance let’s take a look at the steps to find a percentage:
|Step 1||Convert the percentage to a decimal or fraction|
|Step 2||Multiply the decimal or fraction by the whole number|
|Step 3||The result is the percentage of the whole number|
Step-by-Step Guide to Finding Percentage
Step 1: Convert the Percentage to a Decimal or Fraction
Suppose you want to find 30% of 200. The first step is to convert the percentage to a decimal or fraction. To convert a percentage to a decimal, divide it by 100. To convert a percentage to a fraction, put it over 100 and simplify if possible. Therefore, 30% is equivalent to 0.30 or 3/10.
Step 2: Multiply the Decimal or Fraction by the Whole Number
The next step is to multiply the decimal or fraction by the whole number. In this case, we will multiply 0.30 by 200, which gives us 60. Alternatively, we can multiply 3/10 by 200, which also gives us 60. Therefore, 30% of 200 is 60.
Step 3: The Result is the Percentage of the Whole Number
Once you have multiplied the decimal or fraction by the whole number, the result is the percentage of the whole number. In our example, 60 is 30% of 200.
