Answer 3

Calculation of the Weight of 7 Packages

To find the weight of 7 packages, we need to subtract the weight of the 18 packages from the total weight of 82 kilograms.

The weight of the 18 packages is calculated as follows: - There are 18 packages, each weighing 3 kilograms. - Therefore, the total weight of the 18 packages is 18 * 3 = 54 kilograms.

To find the weight of the 7 packages, we subtract 54 kilograms from the total weight of 82 kilograms: - 82 kilograms - 54 kilograms = 28 kilograms.

Therefore, the weight of the 7 packages is 28 kilograms.

Calculation of the Weight of Each of the 7 Packages

To find the weight of each of the 7 packages, we divide the total weight of the 7 packages (28 kilograms) by the number of packages (7).

The weight of each package is calculated as follows: - Total weight of the 7 packages: 28 kilograms - Number of packages: 7 - Weight of each package = Total weight of the 7 packages / Number of packages = 28 kilograms / 7 = 4 kilograms.

Therefore, the weight of each of the 7 packages is 4 kilograms.
