The true statement about the relationships between the number sets is:
Whole numbers include all natural numbers and 0.
Here's a brief explanation of why the other statements are false:
-
Some irrational numbers are also integers. (False: Irrational numbers cannot be integers; integers are whole numbers without fractions or decimals, while irrational numbers cannot be expressed as a fraction.)
-
Not all natural numbers are real numbers. (False: All natural numbers are indeed real numbers.)
-
All rational numbers are also integers. (False: Rational numbers include fractions and decimals that can be expressed as a fraction, whereas integers are whole numbers.)
