    5.45-8.7 = - 3.5

    -3.5:-2.5 = 1.3

    Since you divided by a negative number switch the signs. So it would be A. the first one

    Subtract the 8.7 from the 5.45. then you have - 2.5n>-3.25. divide the - 2.5 to both sides. it's dividing by a negative, so the sign flips and you get, n<1.3 as your answer
