Understanding Decimals and Percentages
Before diving into the conversion process, it is crucial to comprehend what decimals and percentages are.
What are Decimals?
Decimals are a way to represent fractions or parts of a whole using a decimal point. For example:
- 0.5 represents half of a whole.
- 0.75 signifies three-quarters of a whole.
Decimals can range from 0 to 1, and they can also extend beyond one, such as 1.25, which represents one and a quarter.
What are Percentages?
Percentages are a special type of ratio that expresses a number as a fraction of 100. For instance:
- 50% means 50 out of 100.
- 75% indicates 75 out of 100.
Percentages are commonly used in various fields, including finance, statistics, and everyday calculations, making it vital for students to understand how to convert between decimals and percentages.
The Conversion Process: From Decimals to Percents
Converting decimals to percentages is a straightforward process. Here’s a step-by-step guide:
Step 1: Multiply the Decimal by 100
To convert a decimal to a percentage, you need to multiply the decimal by 100. This step helps to shift the decimal point two places to the right.
Step 2: Add the Percent Sign (%)
After multiplying the decimal by 100, the next step is to add the percent sign (%) to denote that the number is now a percentage.
Example of Conversion
Let’s walk through an example to clarify the process:
- Decimal: 0.65
- Step 1: 0.65 × 100 = 65
- Step 2: Add the percent sign: 65%
So, 0.65 as a percentage is 65%.
