Answer:
All natural numbers are also whole numbers.
Step-by-step explanation:
Natural numbers are called counting numbers. They are numbers you can count. Although, Zero is not among them. Neither are negative numbers. Succinctly put, Natural numbers are numbers you can count with the exception of negative numbers and Zero.
Whole numbers are an extension of natural numbers. Unlike Natural numbers although, whole numbers contain Zero. Yet, like natural numbers, that do not contain negative numbers. As a result, we can call them counting numbers that includes Zero.
Now from the above definitions, we can see that
1, whole numbers and natural numbers have many numbers in common. So then, 1 is wrong.
2, all natural numbers are whole numbers, not some. So then, 2 is wrong
3, all whole numbers are not natural numbers, because Zero is a whole number, yet, it's not a natural number.
4, all natural numbers are whole numbers, and this is our answer.
