    Frequently asked questions

    What is 0.75 as a fraction?
    0.75 = 75/100, which simplifies to 3/4. Type 0.75 into the calculator above to see the full step-by-step working.
    How do I convert a repeating decimal like 0.333… to a fraction?
    Type it as 0.(3) — put the repeating digits in parentheses. The calculator uses algebra (let x = 0.333…, then 10x − x = 3, so x = 3/9 = 1/3) and shows the exact fraction, not a rounded guess.
    What does “lowest terms” mean?
    A fraction is in lowest terms when the numerator and denominator share no common factor other than 1. The calculator divides both by their greatest common divisor (GCD), so you always get the simplest form.
    Can I use this for cooking or carpentry measurements?
    Absolutely. Decimals from measuring cups or tape measures convert to kitchen- and workshop-friendly fractions instantly — e.g. 0.125 becomes 1/8 and 2.5 becomes 2 1/2.
    Why did my negative decimal give a negative fraction?
    The sign is preserved: −1.6 converts to −8/5 (or −1 3/5), which is mathematically correct.
    How do I enter a mixed number in the reverse converter?
    Type it as 2 1/2 (whole number, space, fraction). You can also enter plain fractions like 3/4 or improper ones like 11/4.
    Is this decimal to fraction calculator really free?
    Yes — unlimited conversions, no account, no ads in your way, and it works offline once the page loads.
