yes there is!
Yes, if you consider zero to be even.
one (1) and the number itself
Yes.
There is an even number before and after every odd number and vice versa.
Every integer is the number/1 so it can always be described as a ratio between 2 numbers.
Yes, every whole number is an integer.
Yes there is because some numbers which are called odd numbers dont have halfs. But evens do. You cant change it . E.G: 15 Has no half but 16 does 17 doesnt but 18 does...... As u see it goes on and on and on!
3; every number -exept 0- before or behind the comma is significant. Not significant are zeros after numbers that follow the comma; 2.53000000000Also every 0 before numbers before the comma; 00000000032.32 or just 0000253. A zero alone in front of the comma is a significant number
No but every integer is a rational number and numbers that can be expressed as fractions are also rational numbers
No. Consider 15: 1,3,5,15 Every positive whole number has an even number of factors, unless the number is a perfect square.
Because 1 is a factor of every number.
No. Every rational number is not a whole number but every whole number is a rational number. Rational numbers include integers, natural or counting numbers, repeating and terminating decimals and fractions, and whole numbers.
By definition, every even number has 2 as a factor. That means that every set of even numbers will have at least 2 as a common factor. The GCF might be higher, but if it has 2 as a factor, it's even.
