Which of the following is a rational number? Choices: (A)𝜋 (B)4/7 (C)sqrt 10 (D)sqrt 3

Identify Rational Numbers: Identify the rational numbers among the choices. A rational number can be expressed as a fraction where both the numerator and the denominator are integers, and the denominator is not zero. Check Choices: Check each choice: (A) 𝜋 is an irrational number, known for being a non-repeating, non-terminating decimal. (B) 4/7 is a fraction with integers in both the numerator and denominator. (C) sqrt(10) is an irrational number, as 10 is not a perfect square. (D) sqrt(3) is also an irrational number, as 3 is not a perfect square. Final Rational Number: From the checks, only choice (B) 4/7 is a rational number.
