Question

What are the composite numbers between 10 and 30

Answer 1

Answer:

Step-by-step explanation:

A composite number is a number which isn’t 1, and isn’t prime,

Any composite number will be the result of the multiplication of two or more primes

so out of the numbers 1 to 10

1 - neither prime nor composite - a special case (the only number which is neither).

2 - prime

3 - prime

4 - composite - it is 2 * 2

5 - prime

6 - composite - 2 * 3

7 - prime

8 - composite - 2 * 2 * 2

9 - composite - 3 * 3

10 - composite - 2 * 5

so out of the integers 1 to 10

4 are prime (2, 3,5,7)

5 are composite (4,6,8,9,10)

1 is neither composite nor prime.
