Common Fractions to Decimals
What is Fraction to Decimal Conversion?
Converting fractions to decimals is the process of expressing a fraction (a number representing parts of a whole) as a decimal number (a number with a decimal point). This conversion makes it easier to compare values and perform arithmetic operations.
Conversion Methods
1. Division Method
The most straightforward method: divide the numerator by the denominator.
Decimal = Numerator ÷ Denominator
2. Long Division
For fractions that don't divide evenly, use long division to find the decimal equivalent, which may be terminating or repeating.
Types of Decimal Results
Terminating Decimals
Decimals that end after a finite number of digits.
- 1/2 = 0.5
- 3/4 = 0.75
- 7/8 = 0.875
Repeating Decimals
Decimals that have a repeating pattern of digits.
- 1/3 = 0.333... (repeating 3)
- 2/3 = 0.666... (repeating 6)
- 1/7 = 0.142857142857... (repeating 142857)
Common Fraction-Decimal Equivalents
| Fraction | Decimal | Percentage |

| 3/4 | 0.75 | 75% |
| 1/3 | 0.333... | 33.33% |
| 2/3 | 0.666... | 66.67% |
| 1/5 | 0.2 | 20% |
| 2/5 | 0.4 | 40% |
| 3/5 | 0.6 | 60% |
| 4/5 | 0.8 | 80% |
Step-by-Step Conversion Process
Example 1: Convert 3/4 to Decimal
- Divide numerator by denominator: 3 ÷ 4
- 3 ÷ 4 = 0.75
- Result: 3/4 = 0.75
Example 2: Convert 5/8 to Decimal
- Divide numerator by denominator: 5 ÷ 8
- 5 ÷ 8 = 0.625
- Result: 5/8 = 0.625
Example 3: Convert 2/3 to Decimal
- Divide numerator by denominator: 2 ÷ 3
- 2 ÷ 3 = 0.6666...
- Result: 2/3 = 0.666... (repeating decimal)

Frequently Asked Questions (FAQs)
Q: What if the denominator is zero?
A: Division by zero is undefined. The denominator cannot be zero in a valid fraction.
Q: How do I handle repeating decimals?
A: Repeating decimals are shown with ellipsis (...) or with a bar over the repeating digits.
Q: Can all fractions be converted to decimals?
A: Yes, all fractions can be converted to decimals, but some result in repeating decimals that go on infinitely.
Q: What's the difference between fraction and decimal?
A: Fractions show parts of a whole using two numbers (numerator/denominator), while decimals use a base-10 system with a decimal point.
