Converting a fraction to a percentage can be a straightforward process. Here's how to convert 2/5 to a percentage in three easy steps:
Step 1: Convert the Fraction to a Decimal To convert a fraction to a decimal, divide the numerator (2) by the denominator (5).
2 ÷ 5 = 0.4
Step 2: Multiply the Decimal by 100 To convert the decimal to a percentage, multiply it by 100.
0.4 × 100 = 40
Step 3: Add the Percentage Sign Finally, add the percentage sign (%) to the result.
40%
And that's it! 2/5 is equal to 40%.
What is a Fraction?
Before we dive deeper into converting fractions to percentages, let's briefly discuss what a fraction is. A fraction is a way to express a part of a whole. It consists of two parts: the numerator (the top number) and the denominator (the bottom number). The numerator tells us how many equal parts we have, and the denominator tells us how many parts the whole is divided into.
Examples of Fractions
Here are a few examples of fractions:
- 1/2 (one half)
- 3/4 (three quarters)
- 2/3 (two thirds)
Converting Fractions to Decimals
As we saw in Step 1, converting a fraction to a decimal is a simple process. You can use a calculator or perform the division manually.
Why is it Important to Convert Fractions to Decimals?
Converting fractions to decimals is an essential skill in mathematics and everyday life. Decimals are often easier to work with than fractions, especially when performing calculations. Additionally, decimals are used in many real-world applications, such as finance, science, and engineering.
Converting Decimals to Percentages
As we saw in Step 2, converting a decimal to a percentage is a simple process. You can multiply the decimal by 100 or move the decimal point two places to the right.
Why is it Important to Convert Decimals to Percentages?
Converting decimals to percentages is an essential skill in many fields, including business, economics, and statistics. Percentages are often used to express changes, rates, or proportions, making it easier to understand and compare data.
Common Applications of Percentages
Percentages are used in many real-world applications, including:
- Discounts and sales
- Interest rates and investments
- Statistics and data analysis
- Science and engineering
We hope this article has helped you understand how to convert 2/5 to a percentage in three easy steps. Remember to practice converting fractions to decimals and decimals to percentages to become more proficient in these skills.
