No. Double any odd number. The result is even.
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.
No odd numbers are multiples of 4.
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.
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.
No, they are not.
The sum of two odd numbers is always even; the sum of three odd numbers is always odd; the sum of four odd numbers is always even; the sum of five odd numbers is always odd; etc
No. Odd numbers can be written as the sum of consecutive integers, but some multiples of odd numbers are even.
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.
Multiples of 10 are all even numbers.
Multiples of 6 are even composite numbers.
