  1. Step-by-step explanation:

    Given (-7/8)

    Let the required number be x x + (-7/8) = (5/9)

    The LCM of 8 and 9 is 72 x = (5/9) – (-7/8) x = (5/9) + (7/8)

    Consider (5/9) = (5/9) × (8/8) = (40/72)

    Again (7/8) = (7/8) × (9/8) = (63/72)

    On substituting x = (40/72) + (63/72) x

    = (40 + 63)/72

    x = (103/72)
