Answer

The total weight of the other five items is 13.28 kg

Work Step by Step

We can convert 720 g to units of kg. We know that 1 kg = 1000 g. Therefore, we need to move the decimal point 3 places to the left. 720 g = 0.72 kg Let $W$ be the total weight of the other five items. $W + 0.72~kg = 14~kg$ $W = 14~kg-0.72~kg$ $W = 13.28~kg$ The total weight of the other five items is 13.28 kg
