Q. Which of the following are rational numbers?\newlineMulti-select Choices:\newline(A) 00\newline(B) 3.83.8\newline(C) 1010\newline(D)​ Ο€\pi
  1. Define rational number: Step 11: Define a rational number.\newlineA rational number can be expressed as a fractions" target="_blank" class="backlink">fraction where both the numerator and the denominator are integers, and the denominator is not zero. Rational numbers include integers, fractions, and terminating or repeating decimals.
  2. Analyze choice (A): Step 22: Analyze choice (A) which is 00. 00 can be expressed as 01\frac{0}{1}, where 00 is the numerator and 11 is the denominator. Since both are integers and the denominator is not zero, 00 is a rational number.
  3. Analyze choice (B): Step 33: Analyze choice (B) which is 3.83.8. 3.83.8 is a terminating decimal and can be expressed as 3810\frac{38}{10}, which simplifies to 195\frac{19}{5}. Both 1919 and 55 are integers, and the denominator is not zero, so 3.83.8 is a rational number.
  4. Analyze choice (C): Step 44: Analyze choice (C) which is 1010. 1010 is an integer and can be expressed as 101\frac{10}{1}. Since both 1010 and 11 are integers and the denominator is not zero, 1010 is a rational number.
  5. Analyze choice (D): Step 55: Analyze choice (D) which is Ο€\pi (pi).\newlineΟ€\pi is known to be an irrational number because it cannot be expressed as a fraction of two integers. Its decimal representation is non-terminating and non-repeating.
