A rational number can be written as a fraction p/q where q is not 0. For example, 1/2, 3, -4/5.
An irrational number cannot be written as a simple fraction! Examples include √2, √3, and π.
A rational number, written as a decimal, either terminates or repeats (like 0.5 or 0.333...). An irrational number never terminates and never repeats.
Activity: Try classifying these as rational or irrational: 0.75, √4, √5, 2/3.
