    A = 1/2 – 2/3 + 3/4 – 4/5 + 5/6 – 6/7 – 5/6 + 4/5 – 3/4 + 2/3 – 1/2
    =>A = (1/2- 1/2) + (- 2/3 + 2/3) + (3/4- 3/4) +(- 4/5 + 4/5) + (5/6- 5/6) – 6/7
    =>A = 0 + 0 + 0 + 0 + 0 – 6/7
    => A = -6/7
    Vậy A=-6/7

    Giải đáp+Lời giải và giải thích chi tiết:
    A=1/2-2/3+3/4-4/5+5/6-6/7-5/6+4/5-3/4+2/3-1/2
    =(1/2-1/2)-(2/3-2/3)+(3/4-3/4)-(4/5-4/5)+(5/6-5/6)-6/7
    =0-6/7
    =(-6)/7
    vậy A=(-6)/7
