Classifying , 0.47, and 3.605551275ldots as Rational or Irrational
Given the numbers , 0.47, and 3.605551275ldots, classify each as rational or irrational by inspecting its decimal form:
- : The digit repeats endlessly, making it a repeating decimal. Therefore, it is a rational number.
- 0.47: The decimal ends after two digits, making it a terminating decimal. Therefore, it is a rational number.
- 3.605551275ldots: The digits continue without settling into a repeating block and do not terminate. Therefore, this number is irrational.
