When it ends in a five it is odd... When it ends in a zero it is even. 5 Odd 10 Even 15 Odd 20 Even 25 Odd etc...
2 x 2 x 5 = 20 20 is even.
NO because 5 is a factor of 20 and its odd
21+9=20
it would be even. for example 2 times 3 equals 6 and 11 times 20 equals 220 so it would be even
20 is an even number.

There is no such combination to form an even no. 20 by combing 5 odd nos. as odd+odd=even even +even=evenodd+even=odd even+odd=odd adding 5 odd like
they are even
If the sum of two numbers is even, the two numbers are either both even or both odd. A few examples:2 + 4 = 6 (even + even = even)2 + 3 = 5 (even + odd = odd)5 + 2 = 7 (odd + even = odd)7+13 = 20 (odd + odd = even)
If you multiply an odd number by an even number, the product (answer) will be even. Example: 5 x 4 = 20
2 x 2 x 5 = 20 20 is even.
No.. All the numbers end with 0,2,4,6,8 are EVEN NUMBERSso 20 is an even number....
NO because 5 is a factor of 20 and its odd
even number 20 in the alphabet
20 percent more odd then even
The pairs are odd/even and prime/composite. For example, 9 is both odd and composite, whereas 2 is even and prime. (2 is the only even prime.) However, 20=22*5 is composite because it has factors other than itself and one. It is also even, aka not odd, as it has a factor of 2.
