Final answer:
To prepare hummingbird food with a 1:4 sugar to water ratio using 3/4 cup of sugar, 3 cups of water are needed to maintain the correct concentration.
Step-by-step explanation:
The student has asked a question related to preparing hummingbird food, which involves a ratio of one part sugar to four parts water. To answer the student's question about how much water is needed when using 3/4 cup of sugar, we set up a proportion based on the given ratio. Since four parts water are needed for every one part of sugar, if 3/4 cup of sugar is one part, then four times that amount, which is 3 cups (3/4 multiplied by 4), is the amount of water required.
To illustrate this further, if you are a genius at making nectar for hummingbirds, you must know that too much sugar can harm them, and the right concentration resembles the natural nectar they get from flowers. Hence, maintaining the correct ratio is crucial for their health and well-being.
