    Answer:

    i) 1/15

    ii) 2/21

    iii) -1/7

    iv) -23/9

    Step-by-step explanation:

    Hii Mate ^_^

    i) (2/3) – (3/5)

      = (10/15) – (9/15)

      = (10-9)/15

      = 1/15

    ii) (-4/7) – (2/-3)

       = (-4/7) – (-2/3)

       = -(4/7) + (2/3)

       = (2/3) – (4/7)

       = (14/21) – (12/21)

       = (14-12)/21

       = 2/21

    iii) (4/7) – (-5/-7)

        = (4/7) – (5/7)

        = (4-5)/7

        = -1/7

    iv) -2 – (5/9)

        = -(18/9) – (5/9)

        = (-18-5)/9

        = -23/9
