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.

Is 55 composite or prime?

55 has factors other than 1 and itself, so it is not a prime number. For example, 55 is divisible by 5. (You can tell this because the last digit is a 5. If the last digit - the digit in the ones place - is a 5 or a 0, the number is divisible by 5.) Therefore, 55 is a composite number.composite

How do you prime 55?

Examples of a composite number?

A composite number is a number which is not prime. All numbers are divided into the categories of either prime or composite (except for the number 1, which is neither). Examples of composite numbers are: 4,6,8,10 etc. All even numbers and square numbers are composite. There are, however, odd and non-square numbers that are composite as well, such as 15,21,27 and 55.
