• Definition of Rational Numbers: Numbers that can be expressed in the form p/q, where p and q are integers and q ≠ 0.

• Why are Rational Numbers Needed?

  • Some equations, like x + 5 = 5, can be solved using whole numbers.

  • Some equations, like x + 18 = 5, require negative numbers, leading to the introduction of integers.

  • However, equations like 2x = 3 require numbers like 3/2, which are neither whole numbers nor integers, introducing rational numbers.
