Is 4.5 an even number?
No, only integers are classified as even or odd. An even number is one that is divisible by 2. An odd number is a number that is 1 greater than an even number. 4.5 doesn't satisfy either of these.
Is '0' an even number?
Zero is divisible by any number and leaves no remainder. In this it is unique. ( 0/n = 0 ; independent of what "n" is. When a number...say 5, is divided by a pedestrian integer you get quotients like: 1.666 (5/3) or 0.625 (5/8) but divide any number by zero and the quotient is...undefined. Every single time. But some say that every integer must be even or odd, and state, "An integer 'n' is called *even* if there exists an integer m such that n = 2m...From this, it is clear that 0 = (2)(0) is even." Some sources claim zero is neither negative nor positive, while others label it a positive number. It's a positively odd situation that leaves us in a quandary over nothing. Ultimately, we suggest deciding for yourself.
Is -4 an even number?
My dear friend. An even number is an integer which is "evenly divisible" by two. This means that if the integer is divided by 2, it yields no remainder. Zero is an even number because zero divided by two equals zero, which despite not being a natural number, is an integer. Even numbers are either positive or negative.An integer that is not an even number is an odd number. Hope it helped
Is 0 an even number?
In Mathematics we define a number [math]k[/math] an Even numberIf and only if we can able to represent the number[math]k = 2n\forall x \epsilon \Z...............(1)[/math][math]k[/math] an Odd numberIf and only if we represent the number[math]k = (2n+1)\forall x \epsilon \Z.........(2)[/math]where [math]\Z[/math] is the set of all IntegersNow we can’t represent [math]k=0[/math] from equation [math](2)[/math] for any integer value of [math]n[/math]So [math]0[/math] can’t be an Odd numberButwe can represent [math]k=0[/math] from equation [math](1)[/math] for value of [math]n=0[/math]So [math]0[/math] is an Even number==============================================================Did you like my answer?

Is 2.5 odd or even number?
Neither. Why? a.) odd+odd=even b.) odd+even=odd c.) even+even=even 2.5+2.5=5 5 is odd. so odd+even=odd. 2.5 can't be even AND odd. ============================== person below me, I don't quite agree with your reasoning. is 3 an odd number? well yes, but is 3.0 an odd number?
Is 1.4 and even or odd number?
Well to answer this we have to take into account why the Ewoks chose Valentines day to be the 14th of February after the 39th of September stopped existing. They chose the 14th because it is a holy number for them, now if you were to put a decimal point in-between them you get 1.4. Now this is completely un related to your question. The answer is No. because one is an uneven number.
Is 7.5 an odd number or 4.6 an even number?
Shehzaad doesn't paint the whole picture. -3 is an odd number while 0 is an even number. Basically , any integer is either odd or even. Natural numbers are non-zero positive integers, i.e they are just a subset of Integers. 7.5 and 4.6 are not integers and hence don't fall under this classification.
Is 1 an odd or even number?
Well, let's start with even. Any number which can be expressed as 2n is called even. So, any number which has 2 in its prime factors will be called even, rest of the natural numbers are odd. The idea of odd and even numbers is older than the discovery of 0 as a place-holder and as a valid answer for x when solved in an algebraic equation. So, in defining an even as 2n, n cannot be put as 0. Similarly, an odd number being 2n+1 is wrong and it should be 2n-1, making 1 an odd. The first occurrence of 0 is in a Plimpton tablet in Indonesia which represents it as a .(dot). So, the books which tell you that 1 is an odd because 2n+1 can have a possible answer 1 for n = 0 are wrong. Look at the reference:ODD NUMBER and EVEN NUMBER. The Pythagoreans knew of the distinction between odd and even numbers. The Pythagoreans used the term gnomon for the odd number. A fragment of Philolaus (c. 425 B. C.) says that "numbers are of two special kinds, odd and even, with a third, even-odd, arising from a mixture of the two." Euclid, Book 7, definition 6 is "An even number is that which is divisible into two parts.
Is 38 a odd or even number?
It's an even number. Any number that is divisible by 2 is even. Odd numbers cannot be divided by 2. 1 is odd, 2 is even, 3 is odd, 4 is even, 5 is odd, 6 is even... get it? It's easy!
Why is 2 an odd and even number?
First of all, 2 is an even number because it is divisible by 2, as others have previously mentioned. Secondly, others have also stated that 2 is the only even prime number, which is indeed correct.However, we must be clear on what we mean by odd. 2 is odd in that it is the only even prime number. However, in arithmetic, we usually take odd to mean “not divisible by 2”. 2 is not odd in this respect.Not to mention the question of whether -2 is a prime number or not. Of course, it is the product of 2 and -1 which makes it not prime. But then that makes 2 the product of -2 and -1 which would mean 2 is not prime either. This is a debatable topic in mathematics.There is a very interesting (yet childish) way to prove that 2 is an odd number. That is to write it in base 1 (or rather, in a tally system). In this system, writing each number as 1s, 2 becomes 11. 11 in base 10 is an odd number!All child's play aside, one number which may be odd and even is 0.0 is not divisible by 2, yet we call it even. I will allow you to puzzle it for yourself.In conclusion, others have been correct that 2 is both odd and even, but not in the way you would expect, and there are other ways to prove that 2 is indeed an odd number.
