Question

put a check by all the prime numbers.
2
7
13
22
27
29
none of the above

Explanation:

Step1: Recall prime number definition

A prime number is a number greater than 1 that has no positive divisors other than 1 and itself.

Step2: Check each number

• For 2: Divisors are 1 and 2. Prime.
• For 7: Divisors are 1 and 7. Prime.
• For 13: Divisors are 1 and 13. Prime.
• For 22: Divisors are 1, 2, 11, 22. Not prime.
• For 27: Divisors are 1, 3, 9, 27. Not prime.
• For "None of the above": Since 2, 7, 13 are prime, this is false.

Answer:

• $\square$ 2 (checked)
• $\square$ 7 (checked)
• $\square$ 13 (checked)
• $\square$ 22 (not checked)
• $\square$ 27 (not checked)
• $\square$ None of the above (not checked)
