It is: 9
The smallest three digit composite number is 100, and the largest two digit number is 99. 100-99=1.
4/4 = 1
9
The least 1 digit number that is composite is 4. It is because all numbers before that are prime.
The ratio of the number of one-digit prime numbers to the number of one-digit composite numbers is one to one. The one-digit prime numbers are 2, 3, 5, and 7. The one-digit composite numbers are 4, 6, 8, and 9. Therefor, the ratio is 4:4, which simplifies to 1:1.
4, 6, 8 or 9
The largest single digit composite number is 9. The largest prime number is 17 million digits long. The definition of a composite number is any number that has at least one positive divisor other than one or the number itself (it is not a prime number). The largest composite digit is therefore longer than the largest prime number by at leaf +1.
97A 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. 97 is the largest 2 digit prime number.
Yes, 43 is a two-digit odd number because it has two digits and is not divisible by 2. It is a prime number because it can only be divided by 1 and itself. A composite number is a positive integer greater than 1 that has at least one positive divisor other than 1 and itself, so 43 is not a composite number.
A prime number is a number with two and only two factors: 1 (also known as unity) and itself. A composite number is a number with more than two factors; in other words, it has at least one factor besides 1 and itself. 360 has factors other than 1 and itself, so it is not a prime number. For example, it is divisible by 5. (You can tell this because the last digit is a 0. If the last digit - the digit in the ones place - is a 5 or a 0, the number is divisible by 5.) Therefore, 360 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
no it is a prime number (prime means its multiples are only 1 and itself composite numbers can have multiples of many other things)
