Formula Used
1. Greatest Common Divisor
gcd = GCD(|numerator|, |denominator|)
2. Reduced Fraction
Reduced Numerator = Numerator ÷ gcd
Reduced Denominator = Denominator ÷ gcd
3. Mixed Number to Improper Fraction
Improper Numerator = (|whole part| × denominator) + numerator
4. Decimal and Percentage
Decimal = Reduced Numerator ÷ Reduced Denominator, and Percentage = Decimal × 100

FAQs
1. What does reducing a fraction mean?
Reducing a fraction means dividing the numerator and denominator by their greatest common divisor. This keeps the value unchanged while writing it in the simplest possible form.
2. Can this calculator handle mixed numbers?
Yes. Choose mixed-number mode, enter the whole part, numerator, and denominator, and the calculator will convert the value to an improper fraction before simplifying it.
3. What happens if the denominator is negative?
The calculator normalizes the sign by moving the negative sign to the numerator. This creates a standard fraction format that is easier to read and compare.
4. Can zero be simplified?
Yes. Any fraction with a numerator of zero simplifies to 0/1, as long as the denominator is not zero. The reciprocal of zero stays undefined.
5. Why does the calculator show decimal and percentage values?
These outputs help you compare the simplified fraction in other common formats. They are useful in classrooms, reports, ratio analysis, and quick mental checking.
6. What method is used to simplify fractions?
The calculator uses the greatest common divisor, found with the Euclidean algorithm. Then it divides both terms by that value to create the reduced fraction.
7. Does this tool work with improper fractions?
Yes. Improper fractions are supported directly. The calculator reduces them, then also shows the mixed-number form when that representation is useful.
8. Why would I export the result?
Exporting is helpful for homework records, worksheets, audit trails, and documentation. The CSV and PDF options make it easy to store or share the computed result.
