My problem is evaluate the expression -1 11/16 - (-4 1/6)?
1) -27/16 + 25/6 = -81/48 + 200/48 = 119/48 = 2 23/48

2) -1 33/48 + 4 8/48 = 3 41/48

Have to do it two ways, why can't I get the same answer. What am I doing wrong?
Thank you very much

  • Pre Algebra -

    -1 11/16 + 4 1/6

    = - 27/16 + 25/6 sure enough

    = -81/48 + 200/48 agree

    = 119/48

    = 2 23/48 yes
    ============================
    NO!
    -1 33/48 + 4 8/48

    = 3 -25/48

    = 2 + 48/48 -25/48

    = 2 + 23/48
