To convert percentages into decimal form, understanding the process is key, and it can be quite simple once you grasp the concept. In this article, we will specifically look at how to convert 15 percent into its decimal equivalent and provide you with an easy guide for future conversions.
What is a Percentage?
A percentage is a way of expressing a number as a fraction of 100. For example, 15 percent means 15 out of 100. It’s commonly used in various fields like finance, statistics, and education to denote proportional values.
Converting Percentage to Decimal
The formula for converting a percentage to a decimal is straightforward:
Decimal = Percentage ÷ 100
So, to convert 15 percent into decimal form, we simply divide it by 100:
15 ÷ 100 = 0.15
Thus, 15 percent expressed in decimal form is 0.15.
Why Convert Percentages to Decimals?
Simplifying Calculations
