Q. Is 9.3339.333\ldots a rational number?\newlineChoices:\newline(A) yes\newline(B) no
  1. Definition of Rational Number: Understand the definition of a rational number. A rational number is a number that can be expressed as the quotient or fraction pq\frac{p}{q} of two integers, where pp and qq are integers and q0q \neq 0. Rational numbers include terminating decimals and repeating decimals.
  2. Analysis of 9.3339.333\ldots: Analyze the number 9.3339.333\ldots\newlineThe number 9.3339.333\ldots has a repeating decimal. The three dots indicate that the digit '33' repeats indefinitely.
  3. Expressing 9.3339.333\ldots as a Fraction: Determine if 9.3339.333\ldots can be expressed as a fraction.\newlineSince 9.3339.333\ldots is a repeating decimal, it can be expressed as a fraction. To do this, let x=9.333x = 9.333\ldots Then, 10x=93.33310x = 93.333\ldots Subtracting the original number from this, we get 10xx=93.3339.33310x - x = 93.333\ldots - 9.333\ldots, which simplifies to 9x=849x = 84. Therefore, x=849x = \frac{84}{9}, which can be simplified to x=283x = \frac{28}{3}.
  4. Conclusion: Rational Number: Conclude whether 9.3339.333\ldots is a rational number.\newlineSince we have expressed 9.3339.333\ldots as the fraction 283\frac{28}{3}, it is a rational number.
