Exploring Rational Numbers
Objective: To identify a value by its classification in the real number system.

Rational and Irrational Numbers
Rational Number: is a number that can be expressed in the form 𝑎 𝑏 , where a and b are integers and 𝑏≠0. Rational Numbers are positive or negative numbers that are whole numbers, have a terminating decimal, or a repeating pattern decimal. Examples: 7, 1.25, 3.333

Rational and Irrational Numbers
Irrational Number: A number that cannot be expressed in the form 𝑎 𝑏 , where a and b are integers and 𝑏≠0. Irrational numbers have no specific pattern decimal. Example:

Rational Numbers Whole Numbers – consists of all positive whole numbers including zero. {0, 1, 2, 3, 4} Number Set – consists of a specific group of numbers listed from least to greatest. Example: {-1, 3, 5, 8}

Rational Numbers Integers: consists of all positive and negative whole numbers. (including zero) Example: {…-2, -1, 0, 1…} Natural Numbers: also known as “counting numbers”, are all positive whole numbers greater than one. Example: {1, 2, 3, 4…}
