Option (2) will be the correct option.
Answer:
0 and -3
Step-by-step explanation:
Natural numbers are all whole numbers from 1 to infinity. i.e
1, 2, 3, 4 . . .
These numbers do not include 0.
Integers are all whole numbers (positive and negative) including 0. i.e
. . ., -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, . . .
These numbers are all natural numbers including their negative counterparts (i.e negatives of the natural numbers) and also 0.
<em>So from the options in the question:</em>
1 is a natural number as well as an integer
-5.41 is not a natural number neither is it an integer.
3 root 12 (written as ) is neither a natural nor an integer number.
0 is an integer but not a natural number
-3 is an integer but not a natural number
-9/7 is neither a natural nor an integer number.
23 is a natural number as well as an integer
Therefore, 0 and -3 are integers but not natural numbers
