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.

Only one positive prime number has a 5 in the ones digit. That prime number is 5. All other numbers with a 5 in the ones digit are composite because they will be divisible by 5.

The least 1 digit number that is composite is 4. It is because all numbers before that are prime.

43 is a 2 digit odd number but it is a prime number

The 'opposite' status of a number that is not prime is a composite number.Except for 0 and 1, all numbers that are not prime (i.e. they are multiples of other numbers) are called composite numbers.The opposite of a prime number would be a number that is not prime. Almost all numbers that are not prime are composite numbers. A prime number is a number that has exactly two factors. A composite number has more than two factors. However, composite numbers do not include all numbers that are not prime. The number 1 has only one factor, so it is neither prime nor composite - it is unity.

It would probably refer to a digit that is a prime number, or a composite number. Note that mathematicians normally talk about prime and composite NUMBERS, not individual digits.

4/4 = 1

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. yes, there are 8 digit prime numbers.

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.

no it is a prime number (prime means its multiples are only 1 and itself composite numbers can have multiples of many other things)

The smallest three-digit number divisible by the first three prime numbers (2, 3, and 5) and the first three composite numbers (4, 6, and 8) is 120.

Only one positive prime number has a 5 in the ones digit. That prime number is 5. All other numbers with a 5 in the ones digit are composite because they will be divisible by 5.

The least 1 digit number that is composite is 4. It is because all numbers before that are prime.

No composite numbers are prime. A composite number is a number that can be made by multiplying other numbers. A prime number is made only by one and itself. Therefore no number can be both prime and composite

42 is composite, 43 is prime.

No, You can't change a composite number to prime number.
