Answer:

23 and 29 are the prime numbers between 20 and 30.

Step-by-step explanation:

The numbers between 20 and 30 are:

21,22,23,24,25,26,27,28,29

Even numbers, other than 2 are not prime because by definition of being even they are divisible by 2

This then leaves:

21,23,25,27,29

21=3×7- not prime

25=5×5 is not prime number.

27=3×9 is not prime number.

This leaves:

23 , 29 For both of these numbers the only numbers they are evenly divisible by is 1 and themselves.

Therefore, 23 and 29 are the prime numbers between 20 and 30.

Hope it helped you.
