How to Convert Decimal to Fraction

  1. Check the sign: keep the minus sign aside if the number is negative.
  2. Count decimal digits: for a value like 0.875, there are 3 digits after the point.
  3. Remove the decimal point: write the number as an integer over a power of 10, e.g., 875/1000.
  4. Find the GCD: compute the greatest common divisor of numerator and denominator (here it is 125).
  5. Reduce: divide both parts by the GCD to get the simplest fraction, 7/8.
  6. Optional approximation: if the decimal is repeating (e.g., 0.3333), pick a smaller max denominator to get a cleaner fraction such as 1/3.

📌 Examples

  • 0.875 → 7/8 (mixed number: 0 7/8)
  • -1.25 → -5/4 (mixed number: -1 1/4)
  • 0.3333 with max denominator 12 → 1/3

🛠️ When to Use

  • Check math homework or exam steps
  • Resize recipe quantities precisely
  • Convert measurements in CAD/engineering drawings
  • Simplify decimals for woodworking or DIY plans

💡 Tips

  • Lower the max denominator to force a cleaner result for repeating decimals.
  • For whole numbers, the fraction is always number/1.
  • Mixed-number form keeps the sign on the whole part for readability.
