    A)  The number\[\frac{5}{2}\]lies between 2 and 3

    B)  The number\[\frac{11}{12}\] lies between\[\frac{5}{6}\]and\[\frac{23}{24}\]

    C)  The number\[\frac{3}{4}\] lies between \[\frac{2}{3}\] and\[\frac{6}{7}\]

    D)  The number\[\frac{5}{9}\]lies between \[\frac{2}{3}\] and \[\frac{3}{4}\]

    Correct Answer: D

    Solution :

    (d) Take LCM of \[\frac{5}{9},\] \[\frac{2}{3},\] \[\frac{3}{4}\] \[\Rightarrow \] \[\frac{20}{36},\] \[\frac{24}{36},\] \[\frac{27}{36}\] and compare; we can see that \[\frac{20}{36}\] does not lie between \[\frac{24}{36}\]and\[\frac{27}{36}\].
