There are infinitely many such pairs.
For example,
suppose p, q, r and s are 4 prime numbers.
Then p*q and r*s are both composite but p*q and r*s are coprime.
And you could always mutiply either one of them by the prime number t, and maybe the other one by another r to give p*q*t and r2*s. And so on.
So, for example 2*7 = 14
and 3*5 = 15 form such a pair.

Is it true or false that two composite numbers are relatively prime and explain?
Two composite numbers may or may not be relatively prime, depending on their factors. Relatively prime numbers are sets of two or more numbers having 1 as their greatest common factor (gcf). All even numbers have 2 as a common factor, so no even number is relatively prime with any other even number.
45 and 102 relatively prime?
A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite. 45 and 102 are both composite.
If you add a prime number to itself is the the sum composite or prime?
The sum of two prime numbers will be composite unless one of the prime numbers is 2.
Is even numbers composite or prime?
All the even numbers greater than 2 are composite.
Are 2 and 3 relatively prime numbers?
Yes. In general, if you have two different prime numbers, they will also be relatively prime.
Is 2 composite numbers are always relatively prime?
No, they need not be.
Composite relatively prime numbers mean?
Relatively prime numbers share no common factors other than 1.
What are Composite numbers that are relatively prime?
A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite.
Are prime numbers greater than 2 composite?
No. Prime numbers cannot be composite and composite numbers cannot be prime!
Is it true or false that two composite numbers are relatively prime and explain?
Two composite numbers may or may not be relatively prime, depending on their factors. Relatively prime numbers are sets of two or more numbers having 1 as their greatest common factor (gcf). All even numbers have 2 as a common factor, so no even number is relatively prime with any other even number.
Is it true that prime numbers have to be prime and composite?
Prime numbers can not composite as - Prime number has only 2 factors whereas composite have more than 2
Is 2 4 prime numbers?
No they are not prime numbers because 4 is composite.
Is 462 a relatively prime number?
A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite. 462 is composite.
Is 51 and 119 relatively prime?
A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite. 51 is composite, 119 is prime.
Which numbers are prime numbers and which are composite numbers from 1 to 100?
1 is special 2 prime 3 prime 4 composite 5 prime 6 composite 7 prime 8 composite 9 composite 10 composite 11 prime 12 composite ext.
45 and 102 relatively prime?
A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite. 45 and 102 are both composite.
What are prime the numbers and the composite numbers?
A prime number is 2 factors and a composite number is 3 or more!
