Question

To which sets of real numbers does zero belong?
A.natural numbers,integers,and rational numbers
B.natural numbers,integers,and irrational numbers
C.Whole numbers,integers,and irrational numbers
D.Whole numbers,integers,and rational numbers

Answer 1

Zero belongs to the following sets of real numbers:

- Whole numbers (since whole numbers include 0, 1, 2, 3, ...).
- Integers (since integers include negative numbers, zero, and positive numbers).
- Rational numbers (since 0 can be expressed as the fraction 0/1, which is a rational number).

Zero does not belong to the set of natural numbers (which typically start from 1) or to the set of irrational numbers (which cannot be expressed as a fraction).

Therefore, the correct answer is:

D. Whole numbers, integers, and rational numbers.
