coprime numbers with 18 are : 17 and 19.
There is no such thing as a coprime number.Two integers are said to be relatively prime (or coprime) if they have no common positive factor, other than 1. Examples:Any two different prime numbers are coprime.16 and 27 are coprime.14 and 18 are not coprime. They have the common factor 2.
GCF(16, 77) = 1; they are coprime.
16 and 9 are coprime so that the only number going into both is 1.

They are coprime so only 1 does.
18 is 16% of 100*18/16 = 112.5
