Question

The gross weight of a package and it's contents is 11 pounds 5 ounces. If the packaging weights 1 pound 15 ounces, what's the net weight of the content?

Answer 1

16 ounces = 1 pound

so 11 pound 5 ounce package weights 16*11 = 176+5 = 181 ounces

packaging weighs 1 pound 15 ounces = 1*16 = 16+15 = 31 ounces

181-31 = 150 ounces

150/16 = 9.375 pounds = 9 pounds 6 ounces
