🔢 Decimal to Fraction Calculator
DECIMAL TO FRACTION — HOW IT WORKS
A decimal can be converted to a fraction by placing the decimal digits over a power of 10 (e.g., 10, 100, 1000...) and then simplifying. This calculator handles terminating decimals (like 0.75), repeating decimals (like 0.333...), and negative decimals automatically.
📋 HOW TO USE — STEP BY STEP
1. Select Type: Choose Terminating, Repeating, or Negative decimal mode.
2. Enter Value: For terminating/negative, just type the number. For repeating decimals, enter the non-repeating part and the repeating digits separately.
3. Quick Examples: Click any example to auto-fill instantly.
4. Convert: Click "Convert to Fraction" for the simplified fraction, mixed number, equivalent forms, and full step-by-step working.

📐 CONVERSION FORMULAS
Terminating decimal: Move decimal point right until whole number, divide by power of 10. e.g., 0.75 = 75/100 = 3/4
Repeating decimal (all repeating): x = 0.333... → 10x = 3.333... → 9x = 3 → x = 3/9 = 1/3
Repeating decimal (mixed): 0.1333... = 0.1 + 0.0333... = 1/10 + 3/90 = 12/90 = 2/15
Negative decimal: Same steps, apply negative sign at the end. −0.75 = −3/4
Simplification: Divide numerator and denominator by their Greatest Common Divisor (GCD)
📊 COMMON DECIMAL → FRACTION EQUIVALENTS
0.1 = 1/10 | 0.125 = 1/8 | 0.2 = 1/5 | 0.25 = 1/4
0.333... = 1/3 | 0.375 = 3/8 | 0.4 = 2/5 | 0.5 = 1/2
0.6 = 3/5 | 0.625 = 5/8 | 0.666... = 2/3 | 0.75 = 3/4
0.8 = 4/5 | 0.875 = 7/8 | 0.9 = 9/10 | 1.5 = 3/2
⚠️ IMPORTANT NOTES
Irrational numbers: Decimals like π = 3.14159... (non-terminating, non-repeating) cannot be expressed as exact fractions. This tool converts finite decimals and repeating patterns only.
Precision limit: Very long decimals may be rounded by the browser. For maximum accuracy with long decimals, use the repeating decimal mode.
Whole numbers: Whole numbers (no decimal point) are returned as n/1.
Repeating digits: Enter only the repeating block, not the full sequence. For 0.142857142857..., enter repeating = 142857.
