4. Rational Numbers
A rational number is a real number that can be written as a ratio of two integers.
A rational number written in decimal form is terminating or repeating.

5. Examples of Rational Numbers16
1/2
3.56 -8
1.3333…
- 3/4

6. Irrational Numbers
An irrational number is a number that cannot be written as a ratio of two integers.
Irrational numbers written as decimals are non-terminating and non-repeating.

7. Examples of Irrational Numbers
Square roots of non-perfect “squares” Pi 17

8. LET’S PRACTICE! Directions: Write the decimal form of the #
State whether the decimal is terminating, repeating, or nonrepeating.
Decide whether the number is rational or irrational.

11. What are integers? Integers are the whole numbers and their opposites.
Examples of integers are 6
-12
186
-934

12. Integers are rational numbers because they can be written as fraction with 1 as the denominator.
