Hey there!
Often times, natural and whole numbers mean the same thing. The only difference is that, sometimes, zero is considered a whole number and not a natural number. However, even if zero isn't a natural number, all natural numbers are still considered whole numbers. A whole number is any number that doesn't have a remainder, fraction, or decimal, such as 242, 0, or 14, etc.
Your answer is true.
Hope this helped you out! :-)
