In this article, we will explore the concept of converting a percentage to a decimal and provide step-by-step examples to help you understand this concept.
What is a Percentage?
A percentage is a way of expressing a value as a fraction of 100. It is denoted by the symbol "%" and is used to represent a proportion or a ratio. For example, 25% means 25 out of 100, or 0.25 as a decimal.
Converting Percent to Decimal
To convert a percentage to a decimal, you need to divide the percentage value by 100. This can be done using a simple formula:
Decimal = (Percentage / 100)
Example 1: Converting 6% to a Decimal
Let's take the example of converting 6% to a decimal. To do this, we will divide 6 by 100:
6 ÷ 100 = 0.06
Therefore, 6% is equal to 0.06 as a decimal.
Example 2: Converting 25% to a Decimal
Let's take the example of converting 25% to a decimal. To do this, we will divide 25 by 100:
25 ÷ 100 = 0.25
Therefore, 25% is equal to 0.25 as a decimal.
Example 3: Converting 50% to a Decimal
Let's take the example of converting 50% to a decimal. To do this, we will divide 50 by 100:
50 ÷ 100 = 0.5
Therefore, 50% is equal to 0.5 as a decimal.
