Need to convert a fraction to a decimal? Our free Fraction to Decimal Calculator divides the numerator by the denominator instantly, showing the exact decimal, percentage, simplified fraction, and mixed number. It also detects repeating decimals (like 1/3 = 0.(3)) and provides clear step-by-step working — perfect for students, teachers, and everyday math.
Divide the numerator (top number) by the denominator (bottom number). For example, 3/4 = 3 ÷ 4 = 0.75. This calculator does the division for you and also shows the result as a percentage.
A repeating decimal has one or more digits that repeat infinitely. For example, 1/3 = 0.333... written as 0.(3). Any fraction whose denominator has prime factors other than 2 and 5 will produce a repeating decimal.
First convert the fraction to a decimal by dividing numerator by denominator, then multiply by 100. For example, 3/4 = 0.75, and 0.75 × 100 = 75%.
Yes. Enter a negative numerator or denominator (e.g. −3 and 5) and the calculator correctly handles the sign, showing the simplified fraction, decimal, and percentage with the correct sign.
