What are multiples of 9 that are also multiples of 2?
Since the lowest common multiple of 9 and 2 is 18, all of the common multiples of 9 and 2 are multiples of 18. The first five are: 18, 36, 54, 72, 90 Since 9 is odd thean there are going to be odd numbers, which are not multiples of two.
Why is 145 not a LCM of 15 and 18?
There is only one LCM, so it cannot be A lcm, but possibly THE lcm. The LCM of any two (or more) numbers MUST be a multiple of all the numbers. For 15 and 18 the LCM must be a multiple of both 15 and 18. In particular it must be one of the multiples of 18. 18 is an even number, so all its multiples will be even. 145 is an odd number, so it cannot be a multiple of 18 Thus 145 cannot be a multiple of both 15 and 18. Thus it cannot be the LCM of 15 and 18. QED.
Is every multiple of 3 an odd number?
No, 6, 12, 18, 24...are even numbers that are multiples of 3.
What two numbers have a gcf of 18?
Also, any multiples of 18 that differ by 18, like 36 and 54.
What is the common multiple of 18?
In order to have a common multiple, you need to be talking about two or more numbers. The question only asked about one number, 18, so there is no correct answer.
Suppose you roll two dice find the probability of not rolling a multiple of 2?
The result is not a multiple of two if the sum is odd That is, if one die is odd and the other is even That is, die 1 is odd and die 2 even OR die 1 is even and die 2 is odd. There are 18 such combinations So 18 out of a total of 36 = 18/36 = 1/2 So the probability is 0.5 or 50%

Find the smallest multiple of 9 which has no odd numbers?
18 2*9 =18
If the sum is a multiple of 9 and the number is odd and has two digits what will be the numbers?
I can think of a couple that would work. Like 99. 9+9=18 (multiple of 9), it's odd and has two digits. . The full set is 27 45 63 81 99.

How can you divide oddly 18 cows in 9 parts?
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.
