    ABOUT THIS TUTOR ›

    Good morning Selvi,

    Could you verify that the two values are √5/7 and 4/9. I don’t think it makes sense any other way.

    √5/7 < x < 4/9

    square everything

    5/49 < x2 < 16/81

    get a common denominator for the endvalues so we can compare them

    405/3969 < x2 < 784/3969

    Choose 5 numbers between 405 and 784 that are perfect squares.

    x2 = 441/3969, 484/3969, 529/3969, 576/3969, 625/3969

    x = 21/63 ( which reduces to 1/3), 22/63, 23/63, 24/63, 65/63

    These are 5 possible answers

    Answer:

    Step-by-step explanation:

    LCM = 63

    4/9 = 4/9 × 7/7 

     

          = 28/63

    5/7 = 5/7 × 9/9

     

          = 45/63

    ∴ five rational numbers between 4/9 and 5/7 are:

     

          ✪  31/63

          ✪  35/63

          ✪  38/63

          ✪   40/63

          ✪   41/63
