Question

Which statement is the following a counterexample for?

2 ∙ 11 = 22

If you multiply two numbers greater than 5, then their product is greater than 25.
If the product of two numbers is even, then both numbers must be even.
If x ∙ y = 1, then x or y must equal 1.
If two times a number is greater than 16, then the number must be greater than 9.

Answer 2

If the product of two numbers is even, then both numbers must be even.

Answer 3

Since 11 isn't even, is that why?

Answer 4

it's not a because it says "two numbers greater than 5" but one of our numbers isn't 5 so that doesn't apply

b applies because "If the product of two numbers is even, then both numbers must be even." because our product (22) is even but one of our numbers isn't (11)

c doesn't apply because our product isn't 1

d doesn't serve as a counterexample because it's true

Answer 5

I understand now. Thanks Bibby! :-)
