Well, honey, the odd composite factors of 50 are 5 and 25. 5 because it's a Prime number, and 25 because it's just 5 squared. So, you've got those two troublemakers making up the odd composite factors of 50. Hope that clears things up for ya!

50 has six factors: 1, 2, 5, 10, 25 and 50. Odd factors are 1, 5 and 25. Fraction for the odd factors is 3/6 or 1/2. So it means 1/2 of factors of 50 are odd factors.
If an odd number has more than two factors then it is a composite number but if it has only two factors then it is a prime number. Although all prime numbers are odd except for 2 many more odd numbers are composite numbers having more than two factors as for example 21 is an odd number whose factors are 1, 3, 7 and 21.
Composite numbers can have either an odd number or an even number of fractions. Factors of 25 are 1, 5, 25 . (odd number of them) Factors of 26 are 1, 2, 13, and 26 . (even number of them)
Any positive integer with more than two factors is composite.

Incorrect. Square numbers are composite and have an odd number of factors.
