**Reiny**, Thursday, September 13, 2012 at 8:58amYour statement of

"The whole numbers are closed under division" is contradicted by 2 ÷ 10 .

btw , you probably did not mean 10th

since 2 ÷ a 10th

= 2 ÷ 1/10)

= 2 (10/1) = 20 , which would NOT be a counterexample.

**Steve**, Thursday, September 13, 2012 at 10:14amIn fact, it's an incorrect attempt, since you are supposed to be dealing with integers. 1/10 is not an integer, so you can't use it as a divisor.
