math

i'm trying to do a table of values for
9x/5-4/5
if I use 4, my answer is
36/5-4/5
7.25-4/5 = 3.25/5 or .65

is this correct, if not what am I doing wrong?

  1. That doesn't look right.

    First, 36/5 = 7.2 (not 7.25)

    Secondly, you should do all multiplication first, then do subtraction.

    9*4/5 - 4/5
    7.2 - 0.8 = 6.4
