Fraction to Decimal Converter — Common Fractions Reference Table
Convert any fraction to a decimal instantly. Includes a reference table for 1/2 through 15/16, repeating decimals explained, and how to do it by hand.
Converting a fraction to a decimal is just division: divide the top number (numerator) by the bottom number (denominator). 3/4 = 3 ÷ 4 = 0.75. That's the whole method.
The tricky cases are repeating decimals — fractions like 1/3 that don't resolve to a clean decimal. CalcHub's fraction to decimal converter handles those precisely, and the table below covers every common fraction you're likely to encounter.
The Method
decimal = numerator ÷ denominatorExamples:
- 1/2 = 1 ÷ 2 = 0.5
- 3/8 = 3 ÷ 8 = 0.375
- 7/16 = 7 ÷ 16 = 0.4375
- 1/3 = 1 ÷ 3 = 0.3333… (repeating)

| 1/3 | 0.3̄ (0.333…) |
| 2/3 | 0.6̄ (0.666…) |
| 1/6 | 0.16̄ (0.1666…) |
| 1/7 | 0.142857̄ (repeating 6 digits) |
| 1/9 | 0.1̄ (0.111…) |
| 1/11 | 0.09̄ (0.0909…) |
