How this tool works
Fractions are converted to a common denominator for addition or subtraction; multiplication and division use the standard numerator and denominator rules before reduction.
Limits to know
Numerators and denominators are whole numbers; decimal entries are rounded to integers. Denominators cannot be zero, and division by a zero-valued second fraction is undefined.
