Yes.
Yes, they are relatively prime.
12 and 30 are not relatively prime because they have two common prime factors (2 and 3).
No. Both 18 and 33 can be divided by 3, which means that they are not relatively prime.(TIP When someone asks you if the numbers are relatively prime think of a number that both numbers can be divided by to get a whole number. With that you should be able too see strait away which numbersare relatively prime.)(Relatively prime means any amount of numbers that can only be divided by 1 and themselves )Hope I helped! :) XD
no

Yes, 33 and 56 are relatively prime.
The GCF is 33, which means they are not relatively prime.
Yes.
No, 12 and 15 aren't relatively prime, because they both share as a prime factor 3. Dividing both12 and 15 by 3 gives 4 and 5 respectively. Consecutive numbers are always coprime. Coprime numbers are relatively prime to each other, as they share no prime factors, for example 33 and 35,
Yes, e.g. 3 and 5 are relatively prime, 27 (33) and 25 (52) are relatively prime...
