Fraction to decimal converter

What is the conversion of fractions to decimal numbers?

The conversion of fractions to decimal numbers is the free online process of transforming fractional expressions into their decimal equivalents. This process is important since decimals are easier to interpret and use in everyday life, making calculations more straightforward. These conversions typically include both simple and mixed fractions, aiding in simplifying many tasks and equations.

Simple and mixed fractions

Simple fractions

Simple fractions consist of a numerator and a denominator. They represent parts of a whole and are written in the form $\frac{a}{b}$, where $a$ is the numerator and $b$ is the denominator. Simple fractions are easily converted to decimals by dividing the numerator by the denominator. For instance, the fraction $\frac{3}{4}$ converts to the decimal 0.75.

Mixed fractions

Mixed fractions include a whole number and a fractional part, written in the format $c \frac{a}{b}$, where $c$ is the whole number, $a$ is the numerator, and $b$ is the denominator. To convert a mixed fraction to a decimal, you need to combine the whole part and the fractional part. For example, the mixed fraction $2 \frac{1}{2}$ converts to the decimal number by adding the whole part 2 to the fraction $\frac{1}{2}$, resulting in 2.5.

Formula

To convert a fraction $\frac{a}{b}$ to a decimal number, the following division is applied:

For mixed fractions $c \frac{a}{b}$, the formula will be:

Where $a$ is the numerator, $b$ is the denominator, and $c$ is the integer part.

Examples

1. Conversion of simple fractions to decimals:

   • $\frac{3}{5}$ converts to $3 \div 5 = 0.6$.

2. Conversion of mixed fractions to decimals:

   • $1 \frac{3}{4}$ converts to $1 + (3 \div 4) = 1.75$.

3. Conversion of negative fractions:

   • $-\frac{4}{3}$ converts to $-(4 \div 3) = -1.3333 \ldots$.

Notes

• Conversion of fractions can result in recurring decimals. In such cases, it is advisable to round the result to the required number of decimal places.
• The procedure and mathematical operations remain unchanged for negative fractions.

FAQs
