odd
15 is an odd number.
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...
15 is odd since 15/2 = 7.5
Never. When you dont add the same odd number and even number of times. For example: 5 + 3 (2 odd numbers; and even amount of odd numbers ) = 8 5 + 3 + 7 = 15 an odd amount of odd numbers 5 + 3 + 7 + 9 = 24 another even amount of odd numbers. But never if you use the only same number
None. Even and odd numbers are defined only for integers and 1.5 is not an integer.
10 can be divided by 5. 10 is even. 15 can be divided by 5. 15 is odd. So some of the numbers that can be divided by 5 are odd and some are even.
No, it is odd
No, because two odd numbers always add together to be an even number, and a even plus an odd number is an odd number, example: 3+1+11=An even number? 3+1=4 4+11=15 Is 15 even? No. 3+1+11= An odd number (15)
By addition, the sum of an odd number and an even number is always odd. (3 + 2 = 5, 7 + 10000 = 10007 ~ not evenly divisible by 2) By multiplication, an odd number times an even number is always even. (3 x 4 = 12 , 15 x 30 = 450 ~ evenly divisible by 2)
I guess you mean "product" - the product of two odd numbers is odd. (For example, 3x3=9, 5x3=15, etc.
Odd numbers have a special property that when multiplied by any odd number, the product will always be odd. (The only exceptions are for different bases and modulus.) Examples include 3*5=15 35*3=105 127*325=41275
