No, they are not.

Yes.
To be relatively prime, it would have to be compared to another number. When it is, if the GCF, or greatest common factor is 1, then it is relatively prime. 45 and 9 = NO because they have 9 in common. 45 and 31 = Yes because they only have 1 as a common factor.
Yes, 45 and 64 are relatively prime because they do not share any prime factors.
39 and 45 are not relatively prime because they have 3 as a common factor. Relatively prime numbers have no common factor greater than 1.
Since the GCF of 45 and 56 is 1, they are relatively prime.
No, they are not.
No, they are not.
Honey, 45 and 84 are about as prime as a grocery store avocado. They share a common factor of 3, so they are not relatively prime. It's like trying to mix oil and water - just not gonna work out.
