    Arithmetic Expression 2

    Hi All,
    Q. (-3).(4).(-1/6).(-1/12).16

    Ok so P: (-1/6)(-1/12) = (-2/12)(-1/12)= 2/144 = 1/12
    (-3)(4) = -12

    So left with (-12).(1/12).(16)

    Ok so M: (-12).(1/12) = (-12/1)(1/12) - -12/12 = -1.

    Leaving -1.16 = -16.

    The answer is -8/3. Where have I gone wrong?

    Thanks a million.

    2/144 = 1/72, not 1/12.

    Thanks so amending with that change..

    Ok so P: (-1/6)(-1/12) = (-2/12)(-1/12)= 2/144 = 1/72
    (-3)(4) = -12

    So left with (-12).(1/72).(16)

    Ok so M: (-12).(1/72) = (-12/1)(1/72) = -12/72 = -6.

    Leaving -6.16 = -96.

    -12/72 = -1/6, not -6.

    ahhh ...

    Ok so M: (-12).(1/72) = (-12/1)(1/72) = -12/72 = -1/6.

    -1/6.16 = -1/6.16.1 = -16/6 = -8/3.

    Thanks for that, My issue is obviously multiplication of fractions. I'll look it up again.

    I would agree.

    Sounds good!
