No - alternate multiples of 3 are odd, and alternate multiples are 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. When a number is odd, not all of its multiples are odd.Example: 3 is an odd number.Multiples of 3: 3, 6, 9, 12, 15, 18, 21, 24,...Multiples of 3 which are not odd: 6, 12, 18, 24, ...
No. Only odd numbers that are multiples of five.
No, they are not.
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 21.
No, some of them are, some are not.
Any number ending in 5.
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. 6 is a multiple of 3.
That happens because 5 is an odd number. An odd number times an odd number will give you an odd product; an odd number times an even number will give you an even product. The same happens for the multiples of any other odd number.
