Understanding how to convert decimals to fractions is a fundamental math skill. This article will guide you through converting the decimal 0.75 into a fraction, explaining the process step-by-step and providing additional examples. We'll also explore why understanding this conversion is important.

Understanding Decimal Places

Before we begin, let's quickly review decimal places. The number 0.75 has two digits after the decimal point. The first digit (7) represents seven-tenths (7/10), and the second digit (5) represents five-hundredths (5/100). This is crucial for our conversion.

Converting 0.75 to a Fraction: Step-by-Step

1. Write the decimal as a fraction with a denominator of 1: 0.75 can be written as 0.75/1.

2. Multiply the numerator and denominator by 100: This is because there are two digits after the decimal point. Multiplying by 100 moves the decimal point two places to the right, effectively removing it. This gives us (0.75 x 100) / (1 x 100) = 75/100.

3. Simplify the fraction: Both 75 and 100 are divisible by 25. Dividing both the numerator and the denominator by 25 simplifies the fraction to 3/4.

Therefore, 0.75 as a fraction is 3/4.

Why is this Conversion Important?

Converting decimals to fractions is a crucial skill in various fields:

• Baking and Cooking: Many recipes use fractions for precise measurements. Understanding the fractional equivalent of a decimal ensures accuracy.

• Engineering and Construction: Precision is paramount. Converting decimals to fractions helps in calculations involving measurements and proportions.

• Financial Calculations: Understanding fractions is essential for calculating interest rates, proportions, and other financial metrics.

• Mathematics: It's a fundamental concept that underpins more complex mathematical operations.

Other Examples of Decimal to Fraction Conversions

Let's look at a couple more examples to solidify your understanding:

Example 1: Converting 0.25 to a fraction

1. Write as a fraction: 0.25/1
2. Multiply by 100: (0.25 x 100) / (1 x 100) = 25/100
3. Simplify: 25/100 = 1/4

Example 2: Converting 0.6 to a fraction

1. Write as a fraction: 0.6/1
2. Multiply by 10: (0.6 x 10) / (1 x 10) = 6/10
3. Simplify: 6/10 = 3/5

Conclusion

Converting decimals like 0.75 to their fractional equivalent (3/4) is a straightforward process. By understanding the steps involved and practicing with different examples, you can confidently tackle these conversions in various mathematical and real-world applications. Remember, the key is to multiply the numerator and denominator by a power of 10 to eliminate the decimal, and then simplify the resulting fraction to its lowest terms. This skill provides a solid foundation for further mathematical exploration and practical problem-solving.
