Introduction
Percentages are a fundamental concept in mathematics, used to express a value as a fraction of 100. However, in many situations, it's more convenient to work with decimals or fractions. In this article, we'll explore how to match percentages with their equivalent decimals or fractions.
Understanding Percentages
A percentage is a way of expressing a value as a fraction of 100. It's denoted by the symbol "%" and is calculated by dividing a value by 100. For example, 25% is equal to 25 divided by 100, which is 0.25.
Converting Percentages to Decimals
Converting a percentage to a decimal is a straightforward process. To do this, simply divide the percentage value by 100. For example:
- 25% = 25 ÷ 100 = 0.25
- 50% = 50 ÷ 100 = 0.5
- 75% = 75 ÷ 100 = 0.75
Converting Percentages to Fractions
Converting a percentage to a fraction is also a simple process. To do this, divide the percentage value by 100 and simplify the resulting fraction. For example:
- 25% = 25 ÷ 100 = 1/4
- 50% = 50 ÷ 100 = 1/2
- 75% = 75 ÷ 100 = 3/4
Examples of Converting Percentages to Decimals and Fractions
Let's consider some examples of converting percentages to decimals and fractions:
- 12% = 12 ÷ 100 = 0.12 = 3/25
- 18% = 18 ÷ 100 = 0.18 = 9/50
- 22% = 22 ÷ 100 = 0.22 = 11/50
Tips and Tricks
Here are some tips and tricks to help you convert percentages to decimals and fractions:
- Always divide the percentage value by 100 to convert it to a decimal.
- Simplify the resulting fraction when converting a percentage to a fraction.
- Use a calculator to check your answers if you're unsure.
Conclusion
Converting percentages to decimals and fractions is a fundamental skill in mathematics. By following the steps outlined in this article, you'll be able to match percentages with their equivalent decimals or fractions with ease. Remember to always divide the percentage value by 100 to convert it to a decimal, and simplify the resulting fraction when converting a percentage to a fraction.
