Rational vs. Irrational Worksheet
Step 1: Classify each number as rational or irrational.
Step 2: If rational, write the number as a ratio; you do not need to simplify.
If irrational, then explain how you know that the number cannot be written
as a ratio (for example, the radicand is not a perfect square, the given
decimal number goes on forever without repeating, or the expression
involves pi which is an irrational number).
