For repeating decimals like 0.333..., add ... at the end to automatically convert to a fraction.
All fractions are automatically reduced to lowest terms. e.g., 6/8 → 3/4
Improper fractions (numerator > denominator) are also shown as mixed numbers. e.g., 7/4 = 1 3/4

Add ... to the end of the decimal. For example, entering 0.333... automatically converts it to 1/3.
It is a fraction whose numerator and denominator have a greatest common divisor of 1. For example, 6/8 reduces to 3/4. This tool automatically reduces every fraction to its lowest terms.
An improper fraction has a numerator greater than its denominator (for example, 7/4). A mixed number expresses the same value as a whole number plus a proper fraction (for example, 1 3/4).
When the converted decimal is between 0 and 1, its position is displayed visually on the number line.
It is the decimal value multiplied by 100. For example, 3/4 = 0.75 = 75%.
