The multiples of all odd numbers are odd and even. Odd x odd = odd. Odd x even = even. Since odd and even numbers alternate, the multiples will alternate as well.
No. Odd numbers can be written as the sum of consecutive integers, but some multiples of odd numbers are even.
Multiples of 10 are all even numbers.
No. Only odd numbers that are multiples of five.
odd multiples of 7 are odd numbers.. like 7*1, 7*3,7*5..
Numbers that are prime can't be multiples of 10. Multiples of 10 can't be odd.
All odd multiples of 3 are not factors of 8.
All multiples of 6 are even numbers.
That isn't true.
No as 5, 15 and an infinite amount of other multiples of 5 are odd
The multiples of ODD numbers by ODD numbers are ODD. (e.g. 1 x 3, 3 x 3, 5 x 3) Multiplying any number by an EVEN number produces an EVEN number.
All of the odd numbers between 11 and 99 inclusive are two digit numbers that are not multiples of 2. There are 45 of them.
An infinite number. There are an infinite number of odd numbers and the multiple of nine with each one of them is odd. So there are an infinite number of odd multiples of 9.
5, 15, 25, 35
That's a null set. All multiples of 10 are even.
All the even numbers and all the odd multiples of 5.
Multiples of 6 are even composite numbers.
Because not all odd numbers are multiples of 3 - I have shown you below that this is the case and you can see some multiples of 3 are even and some are odd and you can also see that there are even and odd numbers BETWEEN the multiples of 3. 1 (odd) 2 (even) 1*3 =3 (odd) 4 (even) 5 (odd) 2*3 = 6 (even) 7 (odd) 8 (even) 3*3 = 9 (odd) 10 (even) 11 (odd) 4*3 = 12 (even)
No - alternate multiples of 3 are odd, and alternate multiples are even.
43 is an odd number and it is also a prime number
No. Double any odd number. The result is even.
Yes, the factors of all odd numbers are odd numbers.
