Q. Which of the following describe 55? Select all that apply.\newlineMulti-select Choices:\newline(A) natural number\newline(B) real number\newline(C) irrational number\newline(D) whole number
  1. Natural Number Definition: Determine if 55 is a natural number.\newlineNatural numbers are the set of positive integers starting from 11. Since 55 is a positive integer and it is in the set of numbers starting from 11, it is a natural number.
  2. Real Number Definition: Determine if 55 is a real number.\newlineReal numbers include all the rational and irrational numbers. Since 55 can be expressed as a fraction (51\frac{5}{1}), it is a rational number, and hence it is also a real number.
  3. Irrational Number Definition: Determine if 55 is an irrational number.\newlineIrrational numbers are numbers that cannot be expressed as a simple fraction. Since 55 can be expressed as a simple fraction (51\frac{5}{1}), it is not an irrational number.
  4. Whole Number Definition: Determine if 55 is a whole number.\newlineWhole numbers are the set of non-negative integers including 00. Since 55 is a non-negative integer and does not include any fractional or decimal part, it is a whole number.
