Step 1

There are six common sets of numbers.

Natural (Counting) Numbers: ${1, 2, 3, 4, 5, \dots}$

Whole Numbers: Natural Numbers and ${0}$

Integers: ${\dots, - 3, - 2, - 1, 0, 1, 2, 3, \dots}$

Rational Numbers: Integers, Fractions, and Terminating or Repeating Decimals

Irrational Numbers: Non Terminating or Non Repeating Decimals

Real Numbers: Rational Numbers and Irrational Numbers

Step 2

Determine which sets the numbers fit into.

Natural (Counting) Numbers: $11, 13, 5, 15, 14$
