1)   Multiply   each   score   (as   if   it   were   out   of   100)   by   its   percentage.

68   x   .12

=   8.16

72   x   .12

=   8.64

80   x   .12

=   9.6

*(

The   grade   you   have   is   most   likely   out   of   10,   so   multiply   by   10   to   figure   what   it   would   have   been   out   of   100.)

90   x   .10

=   9

2)   Add   all   numbers   from   #1.

8.16

+   8.64

+   9.6

+   9   =   35.4

12   +   12   +   12   +   10   =   46

4)   Divide   #2   by   #3.

Then   move   the   decimal   2   places   to   the   right.

35.4

/   46   =   .76956

76.956

is   the   average.
