Hi Brent,
I have a question.
Why is 3 not divisible by 6.
When 3 divide by 6, the answer is 0.5, which gives you no remainder as well.
Great question!
Great question!
The key here is that, in order for x to be divisible by y, it must be the case that x ÷ y = some integer.
3 ÷ 6 = 0.5, and 0.5 isn't an integer.
Here's how the Official Guide puts it:
If x and y are integers and x ≠ 0, then x is a divisor (factor) of y provided that y = xn for some integer n.
For example, 3 is a divisor of 15, because we can write 15 = (3)(5), where 5 is an integer.
Does that help?
Cheers,
Brent
Hi Brent,
Please help me explain at 01:52, why 6(2k) is divisble by 6 ?
Thanks
The key concept here is as
The key concept here is as follows:
If n and k are integers, and n is a MULTIPLE OF k, we can also say that n is DIVISIBLE by k.
Since we can see that 6(2k) is a multiple of 6, we can also conclude that 6(2k) is divisible by 6.
Does that help?

Great reasoning!
From the first piece of information, we know that N is ODD.
So, the correct answer choice will be the one that evaluates to be an odd number when N is ODD.
Well I didn't chose 3 though

Yes, lots of different numbers will work just as long as they meet the given condition.
