Solution:Concept- The net weight of the package can be calculated by adding the values for the gross weight of the breakfast cereal package's contents and the weight of the packaging.
But first, we'll equalize the terms' units because only terms like nature can be added. To do this, we convert kilograms into grams using the formula 1kg=1000g.
Given information: The gross weight of breakfast is 1 kg and 200 g
15 g for packaging
It is common knowledge that the gross weight of the box's contents plus the weight of the packaging will equal the net weight of a package of morning cereal.
Net weight of the package equals the sum of the gross weight of the contents and the weight of the packaging
The package's net weight = 1 kg200g+15 g.
Adding similar phrases results in,The package's net weight = 1 kg 215 g.
Knowing that 1 kg = 1000 g
Consequently, the package's net weight = 1000g + 215g.
Adding the like terms
The package's net weight = 1215g.
Hence, the correct answer is option 1.
