can natural numbers be decimals like 4.5 and 4.3?

Zero is not a natural number. The natural numbers are 1,2,3,4,...

So, don't count zero or it will be wrong regardless of what your teacher or anyone else says. I know why people get this wrong (for the same reason they think that 1 should be prime...it fits the definition, after all). Just remember: Natural numbers are things you can count...and there has to be at least one of them.

EDIT: In all fairness, I am quite consistent (and insistent) about not including zero. I understand that some mathematicians will want to include zero...best advice...listen to me for your future career in math...but do WHATEVER your teacher does with zero in the debate about natural numbers.

I agree with an earlier poster. If zero were included as a natural number, the set of natural numbers and the set of whole numbers would be the same set (and why would we need a different name).

Think of it this way - the set of whole numbers is the set of natural numbers + the 'hole' number (0), and the set of natural numbers are the numbers which occur in nature. Since 0 doesn't occur (to occur you have to observe it and you can't observe 'nothing') it is not a natural number.

So to answer your question, there are 4 natural numbers on the number line between -6.5 and 4.5, and they are 1, 2, 3 and 4.

Some people call the natural numbers the counting numbers (because we use the same numbers to count with) but the proper name is Natural numbers.

Natural numbers are considered counting numbers. In other words, the set of all non-negative integers. So, no 4.5 and 4.3 are not natural numbers.

0 can be considered a natural number, as are 1, 2, 3, 4, 5, etc...

You should be able to answer your homework question now.

natural numbers are N = {1, 2, 3, 4, 5, ...} not decimals.

between --6.5 and 4.5 there are infinite numbers which are decimals but onlt four natural numbers 1, 2, 3, 4.

The 'natural' numbers are the positive integers (the 'counting numbers') and, unfortunatley, there is no general agreement on whether 0 should be included in the set of natural numbers.

So.... No, numbers such as 4.3 or -6.5 (or even -3) are -not- natural numbers by definition.

No, they are the positive counting numbers starting from either 0 or 1: 0, 1, 2, 3, 4, ...

Natural numbers are ANY numbers from 1 up. As long as it's not negative or zero.

No - natural numbers are 'whole numbers' 'counting numbers'. They can't be negative either.

natural numbers can be decimals as 4.0 , 2.0 ...

No

Natural nos. are positive integers excluding zero.When you include zero it becomes whole nos.

natural nos.={1,2,3}
