MATH
Fractions & mixed numbers calculators
Convert a decimal into an exact reduced fraction, or add, subtract, multiply and divide supplied fractions as decimal numerical values. Choose the job and output format explicitly.
Choose the right tool
Exact decimal-to-fraction tools distinguish terminating and repeating notation. The separate fraction arithmetic tools accept bounded real numerators and positive denominators, and return decimal values without an exact reduction guarantee. For repeating notation, specify how many final digits repeat.
