It is not odd because it is an even number
Here is one possible way: 2 * 1.25 2 * 1.5 5 * 2.5 It is a very odd way of doing it because, in so doing, none of the cows will remain alive. Suppose you could partition the 18 cows into 9 odd groups. Now, Odd + Odd = Even Even + Even = Even and Even + Odd = Odd So, Odd + Odd + Odd + Odd + Odd + Odd + Odd + Odd + Odd = 18 => Even + Even + Even + Even + Odd = 18 => Even + Even + Odd = 18 => Even + Odd = 18 => Odd = 18 which is false. Therefore, it is impossible to partition 18 cows into 9 odd groups.
18 is an even number. not an odd one
9
9
because it is a even number
18
You might answer this in a couple of different ways. 11 is the "odd" one, as it is the only "odd" number, while 4, 12 and 18 are all "even".
18 is an even number.

NO!!!! Any number that ends in 0,2,4,6,8 is EVEN. Any number that ends in 1,3,5,7,9 is ODD. e.g. 1,000,002 is EVEN. 1,111,111 is ODD.

18 2*9 =18
