A 96-kg person contains kg of water. How many kilograms of water are in 84-kg person?

Answer: about 57.12 kg of water
Step-by-step explanation: First, we need to find the unit rate if there are 64 kg of water in a 94 kg person. So we need to do 64 kg of water divided by 94 kg (weight), which is 0.68 [(rounded) actual answer is giant]. That means there is 0.68 kg water in 1 kg. Now we have to do 0.68x84 since we have to figure out how many kilograms of water are in an 84 kg person. 0.68x84=57.12 Therefore, there is about 57.12 kg of water in an 84 kg person.
