Final answer:
To find out how many cups of water each of Lynn's 19 plants will get, divide the 8 cups (a quarter of the 32-cup watering can) by 19, resulting in approximately 0.42 cups of water per plant.
Step-by-step explanation:
To answer the student's question: Lynn has a watering can that holds 32 cups of water, and she fills it a quarter full. Then she waters her 19 plants so that each plant gets the same amount of water. How many cups of water will each plant get? We first have to calculate how much water Lynn has when the can is a quarter full. A quarter of 32 cups is 8 cups of water. Then, we need to divide the 8 cups evenly among her 19 plants. So, we perform the division 8 divided by 19 to get the amount of water per plant, which is about 0.42 cups of water for each plant.
