Here is one way to solve
this problem:
Step 1: Begin
with letter A, 24, and see if 24 is divisible by
more than 1 and itself. 24 is divisible by 2, 3,
4, 6, 8, and 12 as well. Therefore, 24 is not prime.
Continue on with the others.
- 25 is divisible by 5.
- 33 is divisible by 3 and 11.
- 29 is only divisible by 1 and itself, therefore
29 is a prime number. The answer is C.
Step 2: The
explanation of the solution should include a brief
definition of what defines a prime number and the
process clearly stated what was done in step 1.
