Select "Rational" or "Irrational" to classify each number;A. 0.144 Rational or Irrational?B. β0.144 Rational or Irrational?C. β0.0144 Rational or Irrational?
Accepted Solution
A:
βA Number is said to be Rational, if it can be written in the form of [tex]\frac{p}{q}[/tex], otherwise it is Irrational.βDecimal expansion of Rational is either Terminating or Non Terminating Repeating.For example ,0.234, 0.222222........,βDecimal expansion of Irrational is always "Non Terminating non repeating".For example ,β2,β3, 0.23023002300023......., [tex]A.\rightarrow 0.144-----\text{Rational}\\\\B.\rightarrow \sqrt{0.144}\\\\=\sqrt{\frac{144}{1000}}\\\\=\frac{1.2}{\sqrt{10}}-----\text{Irrational}[/tex]ββ΅ ,β10, is Irrational.[tex]C.\rightarrow \sqrt{0.0144}\\\\=\sqrt{\frac{144}{10000}}\\\\=\frac{12}{100}\\\\=0.12-----\text{Rational}[/tex]
