No. Odd numbers can be greater than, smaller than, or equal to prime numbers.

Prime numbers, except 2, are always odd (they would not be prime if they were even cos they would be divisible by 2.) 1 less than any odd number must be an even number.
It is: 3 plus 97 = 100

No. 9 is an odd integer less than 10 and you can get it by multiplying 3X3. All odd integers less than 9 are prime. Except one (1). The number 1 is neither prime nor composite.
Well, darling, the number you're looking for is 15. It's less than 20, odd, and can be broken down into the prime factors 3 and 5. So, there you have it, a prime factor party with the number 15 strutting its stuff.

No, says the number 9.
The converse statement for "odd natural numbers less than 8 are prime" would be "prime numbers less than 8 are odd." But honey, just because a number is odd doesn't mean it's automatically prime. Watch out for those sneaky even primes like 2, they'll throw a wrench in your logic party.
