Q. Which of the following are rational numbers?\newlineMulti-select Choices:\newline(A) 2-2\newline(B) 00\newline(C) 44\newline(D) 6.836.83
  1. Define rational number: Define a rational number.\newlineA rational number is any number that can be expressed as the quotient or fraction pq\frac{p}{q} of two integers, where pp is the numerator and qq is the denominator, and the denominator qq is not zero. Rational numbers include integers, fractions, and terminating or repeating decimals.
  2. Evaluate 2-2: Evaluate choice (A) 2-2. The number 2-2 is an integer, and all integers are rational because they can be expressed as a fraction where the denominator is 11 (e.g., 2/1-2/1).
  3. Evaluate 00: Evaluate choice (B) 00.\newlineThe number 00 is also an integer, and it is rational because it can be expressed as 01\frac{0}{1}.
  4. Evaluate 44: Evaluate choice (C) 44.\newlineThe number 44 is an integer, and like all integers, it is rational because it can be expressed as 41\frac{4}{1}.
  5. Evaluate 6.836.83: Evaluate choice (D) 6.836.83. The number 6.836.83 is a decimal with two digits after the decimal point. It is a terminating decimal and can be expressed as a fraction (683/100)(683/100), which makes it a rational number.
