Question

9/7is rational number or irrational number​

Answer 1

Answer:

9/7 is a RATIONAL number because it fulfills the definition of a rational number: (1.) It can be expressed as the quotient of two integers "a" and "b", i.e., a/b, where b does not equal zero (0); In this case, the integers are 9 and 7, and (2.) it's decimal representation is either repeating or terminating; For 9/7, its decimal representation is repeating: 9/7 = 1.285714285714285714285714 285714285714 ... . On the other hand, an irrational number such as π (pi) has neither of these two characteristics.
