Decimal to Fraction Converter
Turn a decimal like 0.75 into a simplified fraction (3/4), or a fraction into a decimal. Get the mixed-number and improper forms, both reduced.
How to use
In 'Decimal → fraction' mode, type a decimal and get the simplified fraction plus its improper form. In 'Fraction → decimal' mode, enter a numerator and denominator.
Fractions are always reduced using the greatest common divisor, so 6/8 becomes 3/4 and 2.5 becomes 2 1/2.
