Understanding Percentages
Percentages are a way to express a number as a fraction of 100. The term "percent" literally means "per hundred." Therefore, when we say 25%, we are referring to 25 out of 100.
Converting Percentages to Decimals
To convert a percentage to a decimal, you can follow these steps:
- Divide the percentage by 100.
- For example, to convert 25% to a decimal, you would calculate:
- 25 ÷ 100 = 0.25
- This means that 25% is equivalent to 0.25 in decimal form.
Analyzing the Options
Now, let’s evaluate the answer choices:
- a) 0.25 - This is the correct conversion of 25%.
- b) 2.5 - This is 10 times larger than 0.25 and does not represent 25%.
- c) 12 - This is an arbitrary whole number and not related to the conversion.
- d) 25 - This is the percentage itself and does not represent it in decimal form.
Conclusion
Thus, the correct answer is option 'A', which correctly represents 25% as a decimal: 0.25. Understanding this conversion is crucial in various mathematical applications, including calculating discounts, interest rates, and statistics.
