Final answer:
Jada drank 2.25 liters of water and Lin drank 4.5 liters of water.
Step-by-step explanation:
To find out how much water Jada drank, we need to calculate 3/4 of the amount Elena drank. We can do this by multiplying 3/4 by 3 liters.
Jada drank: 3/4 * 3 liters = 9/4 liters = 2.25 liters.
To find out how much water Lin drank, we need to calculate twice the amount Jada drank. We can do this by multiplying 2 by 2.25 liters.
Lin drank: 2 * 2.25 liters = 4.5 liters.
