N, W, Z, Q, R

Practice makes perfect

Before we consider the given number, let's recall the different number sets.

  • Rational Number: A number is a rational number if it can be written in the form ab, where a and b are both integers and b≠ 0.
  • Integer: A number is an integer if it is a positive or negative counting number (or zero). All integers are also rational numbers because any number can be written as a division by one, a1.


  • Whole Number: A number is a whole number if it is a non-negative counting number. All whole numbers are also integers and rational numbers.
  • Natural Number: A number is a natural number if it is a positive counting number. All natural numbers are also whole numbers, integers, and rational numbers.
  • Irrational Number: An irrational number is a number that cannot be written in the form of a rational number. These are recognized as being non-repeating, infinite decimals.
  • Real number: A number is a real number if it is either rational or irrational.

Now, let's try to categorize the given number using these definitions. 62 This is a positive counting number. This means that it is a natural number as well as a whole number, integer, rational number, and real number.
