Problema Solution
Six items purchased at a grocery store weigh 14kg. One of the items in detergent weighing 720 g. What is the total weight, in kg of the other five items?
Answer provided by our tutors
1 kg = 1000 g => 1 g = 10^(-3)kg
thus 720 g = 720*10^(-3) kg = 0.72 kg
the total weight of the other 5 items = the total weight of the 6 items - the detergent weight
the total weight of the other 5 items = 14 - 0.72
the total weight of the other 5 items = 13.28 kg
