Frequently Asked Questions
What is 0.75 as a fraction?
0.75 converts to 3/4 (three-quarters). Our calculator shows you that 0.75 = 75/100, which simplifies to 3/4 when divided by the GCD of 25.
Can I convert repeating decimals?
Yes! Our decimal to fraction calculator handles repeating decimals. For example, 0.333… converts to 1/3. The calculator will identify when a decimal is likely repeating and provide the appropriate fraction.
How do you convert fractions to decimals?
Simply divide the numerator (top number) by the denominator (bottom number). Our calculator does this automatically and shows you the exact steps involved.
Can this calculator handle negative numbers?
Absolutely! Our tool works with both positive and negative decimals and fractions, maintaining the correct sign throughout the conversion process.
What’s the difference between proper and improper fractions?
A proper fraction has a numerator smaller than its denominator (like 3/4), while an improper fraction has a numerator equal to or larger than its denominator (like 7/4). Our calculator converts improper fractions to mixed numbers (7/4 = 1 3/4) for easier reading.

Try It Free NowTips for Manual Conversion (Educational)
While our calculator makes conversions effortless, understanding the manual process helps build mathematical intuition:
Manual Decimal to Fraction Conversion:
- Write down the decimal divided by 1 (e.g., 0.75/1)
- Multiply both top and bottom by 10 for each decimal place (0.75 × 100 = 75/100)
- Find the Greatest Common Divisor (GCD) of numerator and denominator
- Divide both by the GCD to simplify (75÷25 / 100÷25 = 3/4)
Manual Fraction to Decimal Conversion:
- Divide the numerator by the denominator using long division
- Continue until you get a terminating decimal or identify a repeating pattern
- Round to desired decimal places if necessary
Of course, using our fraction calculator is much faster and eliminates the risk of arithmetic errors!
