All those numbers are mutually prime (5 and 7 are prime, full stop), so the least common denominator is 5x7x8x9.
The prime numbers (factors) of 75 are: 3 and 5
5,1
5. And primes must be integers.
Prime numbers are: 2 3 5 7 Composite numbers are: 4 6 8 9 10 So the ratio is: 4 to 5

9 is not prime. 9 = 3 * 38 is not prime. 8 = 2 * 2 * 2

5 is a prime number, but not 9, because you can do 3*3=9
No neither of them are because 3x3=9 so it is not prime. 8 is not either because 2x4=8
No.
composite 9 is prime
no neither are prime
Co-prime numbers are those that do not share a greatest common denominator larger than 1. The list of single digit co-primes is below (note that each co-prime also has a conjunctive, where the terms are reversed) (1, 1)(1, 2)(1, 3)(1, 4)(1, 5)(1, 6)(1, 7)(1, 8)(1, 9)(2, 1)(2, 3)(2, 5)(2, 7)(2, 9)(3, 1)(3, 2)(3, 4)(3, 5)(3, 7)(3, 8)(4, 1)(4, 3)(4, 5)(4, 7)(4, 9)(5, 1)(5, 2)(5, 3)(5, 4)(5, 6)(5, 7)(5, 8)(5, 9)(6, 1)(6, 5)(6, 7)(7, 1)(7, 2)(7, 3)(7, 4)(7, 5)(7, 6)(7, 8)(7, 9)(8, 1)(8, 3)(8, 5)(8, 7)(8, 9)(9, 1)(9, 2)(9, 4)(9, 5)(9, 7)(9, 8)
