No, 75 and 625 are not relatively prime. No pair of numbers that both end in 5 can be relatively prime.

No, since they are not relatively prime.

No, 5 is a common factor to both.

They are both divisible by 3, 5 and 15.

I'm uncertain about what you mean by "relatively", but 75 and 99 are not prime. Factors of 75: 1, 3, 5, 15, 25 and 75 Factors of 99: 1, 9, 11 and 99

No they are not...

No.

No, 60 and 75 are not relatively prime because their greatest common factor is 15 and not 1. In order for them to be relatively prime, 1 must be their greatest common factor.

The short answer is yes, 75 and 112 are relatively prime. The long answer is that any two numbers are considered to be relatively prime if they have no common factors other than 1. The prime factors of 75 are 3, 5, 5 since 3 x 5 x 5 = 75. The prime factors of 112 are 2, 2, 2, 2, 7 since 2 x 2 x 2 x 2 x 7 = 112. As you can see, there are no numbers in common in these lists of factors. Knowing this test, you can now determine for yourself if any set of numbers is relatively prime.

Yes.

Yes.
