    Answer:

    -3 / 4 , 5 / 12 , – 7 / 16 , 9 / – 24

    = > – 3 / 4 , 5 / – 12 x ( -1 ) ( -1 ) , -7 , 16 , 9 , 16 x ( -1 ) ( -1 ) .

    = > – 3 / 4 , – 5 / – 12 , -7 / 16 , – 9 / 24 .

    = > – 3 / 4 = – 3 x 12 , 4 x 12 = – 36 / 48 .

    = > – 5 / 12 = – 5 x 4 , 12 x 4 = – 20 / 48 .

    = > – 7 / 16 = – 7 x 3 , 16 x 3 = -21 / 48 .

    = > – 9 / 24 = – 9 x 2 , 24 x 2 = – 18 / 48 .

    – 36 / 48 < – 21 / 48 < – 20 / 48 < – 18 / 48 .

    – 3 / 4 < – 7 / 16 < – 5 / 12 < – 9 / 24 .

    Step-by-step explanation:

    to do so, we first equalize denominators of all rational numbers....

    we should find out the common factor of all rationals...

    1) 2/3 × 12/12 = 24/36

    4/9 × 4/4 = 16/36

    5/12 × 3/3 = 15/36

    7/18 × 2/2 = 14/36

    so, we can find descending order now easily,

    14/36, 15/36, 16/36, 24/36

    =7/18, 5/12, 4/9, 2/3

    2) 3/4 × 12/12 = 36/48

    5/12 × 4/4 = 20/48

    7/16 × 3/3 = 21/48

    9/24 × 2/2 = 18/48

    as usual,

    18/48, 20/48, 21/48, 36/48

    = 9/24, 5/12, 7/16, 3/4

    HOPE THIS HELPS U.......

    AND U FELT HAPPY........

    I DID IT WITH MY PLEASURE......
