Answer by JulietG(1812)   (Show Source):
You can put this solution on YOUR website! Natural numbers are "counting numbers". They are positive whole numbers that you would use to count objects.
.
Which of those fall under that definition? If you were counting apples, what could you use to count them?
.
7 is obvious.
The negatives are obviously not.
What about 0? Can you "count" zero? The true answer is "no", although I have seen texts that dispute that. It's not a natural number. You don't start counting with zero, you start with "one".
 is not a whole number, so no. No for 7.8 for the same reason.
What about the square root of 25? Tricky :-). It's 5, so it IS a natural number. Whether you write it as sq rt 25 or 5, it's the same number.
