Answer 2

Answer:

1) 25,30 - no

2) 5,7 - yes

Step-by-step explanation:

Co primes means that the numbers have no common factor other than 1.

25 and 30 have 5 and 1 as factors. They have a common factor other than 1 i.e.,5. Therefore, they are not coprimes.

On the other hand, 5 and 7 have only 1 as common factor . Hence, they are coprimes.
