  • Question
  • 5/6 ÷ 6/7 x? - 8/9 ÷ 1 3/ 5 + 3/4 x 3 1/ 3 = 2 7/ 9


  • Options
  • A. 7/6
  • B. 6/7
  • C. 1
  • D. None of these

  • Correct Answer
  • 6/7 

    Explanation

    Let 5/6 ÷ 6/7 x N - 8/9 ÷ 8/5 + 3/4 x 10/3 = 25 / 9
    Then, 5/6 x 7/6 x N - 8/9 x 5/8 + 5/2 = 25/9
    ? 35N / 36 = 25/9 + 5/9 - 5/2
    ? 35N / 36 = (50 + 10 - 45) / 18 = 5/6
    ? N = (5/6 x 36/35) = 6/7
