2/3
It is 2/3.
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).
No. To simplify a fraction the numerator and denominator must have a common factor greater than 1.
To simplify a fraction using prime numbers, find the prime factors of both the numerator and denominator. Then, divide the numerator and denominator by their common prime factors. Repeat this process until there are no common prime factors left. The resulting fraction will be simplified to its simplest form.
A proper fraction with the numerator and denominator going to make a product of 119 is 7/17.
Yes. If the numerator and denominator of a fraction are prime, the fraction is in simplest form. The reason is that each number has only two factors, 1 and the number itself. For that reason, it is not possible for the numerator and denominator to have any factors (other than 1) in common.
Yes, if the denominator is a multiple of the numerator. No, if not.
2/2
No, prime refers to whole numbers. In the situation you describe, a fraction is in its simplest form.
Their GCF is 1.
simplest form
You have to make sure both the numerator and denominator are prime numbers, and if they aren't, then it's not in simplest form. Also, the denominator shouldn't be divisible by the numerator, which sort of falls in to the prime number category. Hope this helped. :) I'm really good with numbers. :)
