Decimal to Fraction Calculator
Type a decimal (like 0.375) and get the equivalent fraction in lowest terms, with the steps.
How It Works
Every terminating decimal is a fraction whose denominator is a power of ten. The calculator writes your decimal over 10, 100, or 1,000 (one zero per decimal digit), then divides the top and bottom by their greatest common factor to reach lowest terms — the same steps you would show on paper.
Frequently Asked Questions
Does it work for negative decimals?
Yes — the sign is kept and applied to the final fraction.
What about repeating decimals like 0.333…?
Enter the rounded value you have (e.g. 0.3333). For exact repeating decimals, the true fraction is found algebraically (0.333… = 1/3).
Why lowest terms?
A fraction in lowest terms is the standard simplified answer — top and bottom share no common factor except 1.
