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.

21, 55, 77, and 93 are composite numbers. 23 is a prime.

composite because it has more than two factors

Prime numbers are numbers that can only be multiplied itself and one.For ex.87 is a prime number. You can't multiply a number to get 87. Composite is a number that can be multiplied by other numbers than itself. For ex.55 is a commposite number. 11 and 5 can get you 55. Hope u understand! Good luck!

composite because it has more than two factors

55 is a composite number because it has other factors aside from 1 and itself. The other factors of 55 are 5 and 11.

Every number greater than 5 that ends in a 5 is a composite number, not a prime.

Prime factorization means to change a composite number into the product of its prime factors as for example 55 as a product of its prime factors is 5*11 = 55

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.

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

To find the prime factorization of a number, start with any factor pair of that number and keep factoring the composite numbers until all factors are prime. 55 5 x 11 = 55 Both factors are prime, so that is the prime factorization.

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.

It is not a prime number, it is a composite number.
