If the numerator and denominator are prime numbers and not equal then they don't have common factors (except 1 which would be a common factor even if the numerator and denominator were prime numbers).
The idea is to divide numerator and denominator of a fraction by any common factors. Prime factorization is simply used to find all possible factors.

The tree method is a diagram that does not display properly in this answer area.
Prime factors are factors that are also prime numbers.
first you do the prime factorization 65 and 91.Then with the answers you get idk wat to do with them sry
5 x 5 x 11 = 2755 x 11 x 11 = 605Both have a 5 and an 11 in common. Take them out. The result is 5/11
First reduce the fraction to its simplest form. If the denominator has any prime factor other than 2 or 5 then it is a repeating decimal. Otherwise it terminates.
If the numerator and denominator are prime numbers and not equal then they don't have common factors (except 1 which would be a common factor even if the numerator and denominator were prime numbers).

The prime factors of 99 are 3 and 11

It is called simplification.
19 is a prime number, as its only factors are 1 and 19.Since you cannot divide anything out of 19, the fraction cannot be reduced.
a number with only 2 factors (1 and itself ) is called a prime number
this can be done by the prime factorization method 5x43
