Annue must send two packages. One package weighs 11 1/8 lbs. and the other weighs 9 1/5 lbs. what is the total weight of the two packages?
Is it 23 1/8 lb?

You should realize this can't be right. 11 plus 9 was 20 when I went to school. 1/8 + 1/5 is less than 1/2.
Please try again. 
Ok so then I think it would be 20 1/20, right,
because the fractions add is 2/40 which reduces to 1/20? therefore making it 20 1/20 lbs???? 
1/8 = 5/40
1/5 = 8/40
5/40 + 8/40 = 13/40
Your packages weigh 20 13/40 pounds
