The gross weight of a package and its contents is 11 pounds 5 ounces. if the packaging weighs 1 pound 15 ounces, what's the net weight of the contents?

11 lbs 5 oz - 1 lb 15 oz...we are gonna have to borrow...there is 16 oz in a lb.
11 lbs 5 ozwe r going to borrow 1 lb from the right side and add it to the left side making it 10 lbs and 21 oz...u see what I did...I borrowed 1 lb from the right side and added 16 oz to the left.Now we can subtract.

10 lbs 21 oz - 1 lb 15 oz = 9 lbs 6 oz <== ur answer

Net weight:

11 pounds 5 ounces - 1 pound 15 ounces.

10 pounds + (1 pound 5 ounces) - 1 pound 15 ounces.

Note 1 pound = 16 ounces

10 pounds + (16 ounces + 5 ounces) - 1 pound 15 ounces.

10 pounds + (21 ounces) - 1 pound 15 ounces.

10 pounds - 1 pound = 9 pounds         21 ounces - 15 ounces  = 6 ounces

9 pounds 6 ounces.

Net weight =  9 pounds 6 ounces.

Ibelieve it would be letter c (:
