Answer: YES!

Explanation:

The greatest common factor (GCF) of 1 and 15 is 1. Convert 1/15 to its simplest form by dividing the numerator and denominator by its GCF

The prime factors of 15 are all the prime numbers that you multiply together to get 15. The prime factors of 15 are:

3 x 5

A fraction is a repeating decimal if the prime factors of the denominator of the fraction in its lowest form do not only contain 2s and/or 5s or do not have any prime factors at all. This is the case here, which means that our answer is as follows:

1/15

= repeating
