Question

When the product is odd, can either factor be even? How do you know?

Answer 1

No.

Step-by-step explanation:

Any number times an even number is even by definition.

Let's call the even factor 2n, and the other factor (odd or even) x. 2n × x = 2nx. Because it is multiplied by 2, it must still be even. The factors of an odd number are all odd.
