    Remember, when dividing fracitons, invert and multiply or

    (a/b) / (c/d) = (a/b) (d/c) = (ad) / (bc)

    also, (+) / (-) = (-)

    convert - 0.35 to fraction

    -0.35=-0.35/1=-3.5/10=-35/100

    now we have

    (8/15) / (-35/100)

    we know the end result is negative so discard that

    (8/15) / (35/100)

    35/100 simpifies to 7/20

    (8/15) / (7/20)

    invert ane multiply

    (8/15) (20/7)

    (8*20) / (15*7)

    160/105

    32/21

    negative

    -32/21

    B is answer
