Introduction

In mathematics, converting fractions to decimal fractions and calculating percentages are essential skills that are used in various real-world applications. In this article, we will discuss how to convert a fraction to a decimal fraction and calculate a percentage of a given value.

Converting a Fraction to a Decimal Fraction

A fraction is a way of expressing a part of a whole as a ratio of two numbers. For example, the fraction $\frac{5}{8}$ represents five-eighths of a whole. To convert a fraction to a decimal fraction, we divide the numerator (the top number) by the denominator (the bottom number).

Example 1: Converting $\frac{5}{8}$ to a Decimal Fraction

To convert the fraction $\frac{5}{8}$ to a decimal fraction, we divide the numerator (5) by the denominator (8).

\frac{5}{8} = 5 ÷ 8 = 0.625

We can also use a calculator to convert the fraction to a decimal fraction.

Example 2: Converting $\frac{3}{4}$ to a Decimal Fraction

To convert the fraction $\frac{3}{4}$ to a decimal fraction, we divide the numerator (3) by the denominator (4).

\frac{3}{4} = 3 ÷ 4 = 0.75

Calculating a Percentage of a Given Value

A percentage is a way of expressing a part of a whole as a fraction of 100. For example, 30% is equal to $\frac{30}{100}$ or 0.3. To calculate a percentage of a given value, we multiply the value by the percentage.

Example 1: Calculating 30% of 500 kg

To calculate 30% of 500 kg, we multiply 500 kg by 0.3.

30 \% \text{ of } 500 \text{ kg} = 500 \text{ kg} \times 0.3 = 150 \text{ kg}

We can also use a calculator to calculate the percentage.

Example 2: Calculating 25% of 2000

To calculate 25% of 2000, we multiply 2000 by 0.25.

25 \% \text{ of } 2000 = 2000 \times 0.25 = 500

Discussion

Converting fractions to decimal fractions and calculating percentages are essential skills that are used in various real-world applications. In this article, we discussed how to convert a fraction to a decimal fraction and calculate a percentage of a given value. We also provided examples of how to convert fractions to decimal fractions and calculate percentages using a calculator.

Conclusion

In conclusion, converting fractions to decimal fractions and calculating percentages are essential skills that are used in various real-world applications. By following the steps outlined in this article, you can convert fractions to decimal fractions and calculate percentages with ease.
