Rational Numbers  

Irrational Numbers   ‘t Anything that results in a non-repeating, non-terminating decimal is irrational. If the decimal stops or repeats, it’s rational.

Operations Classify the following as rational or irrational: 1) 2) 3) Why do you think this is? Is there a rule we can follow?
