Solution: The number -1 is an integer that is NOT a whole number. This makes the statement FALSE. Example 3: Tell if the statement is true or false. The number zero (0) is a rational number. Solution: The number zero can be written as a ratio of two integers, thus it is indeed a rational number. This statement is TRUE.
