Q. Which of the following is a whole number?\newlineChoices:\newline(A) 55\newline(B) 2-2\newline(C) 13\frac{1}{3}\newline(D) 4.354.35
  1. 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.
  2. Evaluate Choices: Evaluate each choice to determine if it is a whole number.\newline(A) 55 is a positive integer without any fractional or decimal part.
  3. Check if 55 is Whole Number: Check if 55 is a whole number.\newlineSince 55 is a positive integer and has no fractional or decimal part, it is a whole number.
  4. Evaluate Other Choices: Evaluate the other choices for completeness.\newline(B) 2-2 is an integer but it is negative, so it is not a whole number.\newline(C) 13\frac{1}{3} is a fraction, so it is not a whole number.\newline(D) 4.354.35 has a decimal part, so it is not a whole number.
  5. Conclude Whole Number Choice: Conclude which choice is a whole number. Based on the definition and evaluation of each choice, (A)5(A) \, 5 is the only whole number among the given choices.
