To reduce a fraction, divide both its numerator and denominator by their greatest common factor, GCF.
Calculate the greatest (highest) common factor (divisor), gcf, hcf, gcd.
Integer numbers prime factorization:
9 = 32;
11 is a prime number, it cannot be broken down to other prime factors;
Multiply all the common prime factors, by the lowest exponents.
But the two numbers have no common prime factors.
gcf, hcf, gcd (9; 11) = 1;
coprime numbers (relatively prime);
Fraction's numerator and denominator are coprime numbers (no common prime factors). Fraction cannot be reduced (simplified) - irreducible.
Rewrite the fraction:
As a decimal number:
9 ÷ 11 =
As a percentage:
