If 7/21 of a number is 6, what is 14/21 of that number?
Answer: 12

Let the number be x. Given 7/21 * x = 6 → (1/3)x = 6 → x = 18. Then, 14/21 * x = (2/3) * 18 = 12. Studying this highlights proportional reasoning, the challenges of fraction calculations, and its impact on problem-solving. For Pakistan, this provides lessons for teaching fractions in math education, enhancing analytical skills for STEM fields and competitive exams like CSS, and ensuring precision in calculations.
