Q. Which of the following describe 66? Select all that apply.\newlineMulti-select Choices:\newline(A) real number\newline(B) integer\newline(C) natural number\newline(D) irrational number
  1. Real Number: Determine if 66 is a real number.\newlineAll integers, fractions, rational, and irrational numbers are real numbers. Since 66 is an integer, it is also a real number.
  2. Integer: Determine if 66 is an integer.\newlineAn integer is any whole number, including negative numbers, zero, and positive numbers. Since 66 is a whole number without a fractional or decimal part, it is an integer.
  3. Natural Number: Determine if 66 is a natural number.\newlineNatural numbers are the set of positive integers starting from 11. Since 66 is a positive integer and greater than 11, it is a natural number.
  4. Irrational Number: Determine if 66 is an irrational number.\newlineAn irrational number is a number that cannot be expressed as a simple fraction. Irrational numbers have non-repeating, non-terminating decimal parts. Since 66 can be expressed as the fraction 61\frac{6}{1} and does not have a non-repeating, non-terminating decimal part, it is not an irrational number.
