Oh, what a happy little question! Let's take a look at those numbers between 11 and 20 that are composite, which means they have more than two factors. We have 12, 14, 15, 16, 18, and 20. Each one is unique and adds a lovely variety to our number family. Just like in painting, each number has its own special charm!
The composite numbers between 11 and 29 are 12,14,15,16,18,20,21,22,24,25,26,27 & 28.
All numbers other than 11, 13 ,17, 19 ,23,29, 31 are composite numbers. eg 10,12,14,15, are composite numbers.
11, 13, 17, 19, 23, 29 are the primes between 10 and 30 so the composite numbers are all the others. 12,14,15,16,18,20,21,22,24,25,26,27,28, and 30 are the composite numbers between 10 and 30.
The composite numbers between 11 and 19 are 12, 14, 15, 16 and 18
12, 14, 15, 16, 18, 20, 21, 22
The composite numbers between 11 and 19 are: 12 14 15 16 18 The other numbers, 11, 13, 17, and 19, are all prime.
The composite numbers between 11 and 29 are 12,14,15,16,18,20,21,22,24,25,26,27 & 28.
39
All numbers other than 11, 13 ,17, 19 ,23,29, 31 are composite numbers. eg 10,12,14,15, are composite numbers.
composite numbers between 11 and 21:12 14 15 16 18
Their sum is 37.
11, 13, 17, 19, 23, 29 are the primes between 10 and 30 so the composite numbers are all the others. 12,14,15,16,18,20,21,22,24,25,26,27,28, and 30 are the composite numbers between 10 and 30.
15 is a composite number - it can be divided by 3 and 5. 11, 13, 17 and 19 are all prime numbers, not composite.
11 is a prime and contains no composite numbers.
None of the numbers 7, 11, and 13 are composite numbers; they are all primes.
12, 14, 15, 16, and 18 are composite numbers 11, 13, 17, and 19 are prime numbers
The composite numbers between 11 and 19 are 12, 14, 15, 16 and 18
