Let's analyze each of the statements you've provided:
-
Whole numbers include all natural numbers and 0.
This statement is true. Whole numbers are defined as the set of natural numbers (1, 2, 3, ...) along with 0. Thus, whole numbers include 0 and all natural numbers. -
Not all natural numbers are also integers.
This statement is false. All natural numbers (which typically include 1, 2, 3, ...) are indeed integers. The set of integers includes all natural numbers, 0, and the negative integers (-1, -2, -3, ...). -
All rational numbers are also integers.
This statement is false. Rational numbers are any numbers that can be expressed as the quotient of two integers, but they include fractions (like 1/2, 3/4), which are not integers. Only some rational numbers are integers (like 1, -5, 0).
In summary, only the first statement is true.
