Definition of Whole Number: Understand the definition of a whole number. Whole numbers are non-negative numbers without any fractional or decimal parts. They include all the positive integers along with zero.
Evaluate Choices: Evaluate each choice to determine if it is a whole number.(A) 21 is a fraction and not a whole number.
Evaluate (A): Evaluate choice (B).(B) –8 is a negative integer and not a whole number because whole numbers cannot be negative.
Evaluate (B): Evaluate choice (C).(C) 106 is a fraction and not a whole number.
Evaluate (C): Evaluate choice (D).(D) 0 is a non-negative integer and it does not have any fractional or decimal part. Therefore, it is a whole number.
Evaluate (D): Choose the correct answer based on the evaluations.The only choice that is a whole number is (D)0.
