5.5 is neither because it must be a whole 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.

Is 55 a prime number or a composite number?

Answer:55 is not a prime number. It is a composite number.Definition:A prime number has exactly two factors: 1 (also known as unity) and itself. A composite number has more than two factors; in other words, it has at least one factor besides 1 and itself.Explanation:Any number ending in 0 or 5 is evenly divisible by 5, so it has 5 as a factor. Thus, 55 is also divisible by 5, so it is a composite number.
