Which of the following statements is incorrect?

A
Real numbers can be negative.

B
All whole numbers are natural numbers.

C
All rational numbers are real numbers.

D
Irrational numbers cannot be written as the ratio of two integers.

Solution

Whole numbers are the numbers 0, 1, 2, 3, 4, and so on (the natural numbers and zero). Negative numbers are not considered whole numbers. All natural numbers are whole numbers, but not all whole numbers are natural numbers since zero is a whole number but not a natural number.
