Question

Which of the following numbers is prime?

6
7
12
15

Answer 1

the answer is 7, because you cannot multiply any number besides itself and 1 to equal 7.

Answer 2

7 is the prime number.

A prime number is something that nothing can be multiplied.

3x2 = 6

6x2=12

3x5 = 15

7x1 = 7

So your correct answer is 7.
