$\:$

Answer:

Two integers a and b are said to be coprimes if they have no common factors other than 1 and the number itself.

Hence their HCF(Highest common factor) is 1.

Here, (18,25) is a coprime.

Prime factorisation of:

18= 2×3×3

25= 5×5

18 and 25 have no common factor other than 1.

=>HCF(18,25)=1

Yes, (18,25) are coprime numbers.
