Fraction Simplifier
Reduce a fraction to its lowest terms.
Worth Knowing
Simplifying a fraction means dividing the numerator and denominator by their greatest common divisor, producing the unique lowest-terms form. This matters for comparison — it's hard to see at a glance that 18/24 and 15/20 are equal until both reduce to 3/4. Reduced fractions also make further arithmetic lighter and results easier to interpret, which is why most textbooks and exams expect final answers in lowest terms.
