Explain the most efficient method for measuring each ingredient using only 1 1 the following two measuring cups: cup and cup. You can use one or 3 4 both of the measuring cups. ingredients - 1/2,1 3/4,2 1/4,2 5/2

To measure each ingredient using only 1 or both of the measuring cups (1 cup and 3/4 cup), we can follow these steps:

1. For 1/2 cup: Since we don't have a 1/2 cup measuring cup, we can use the 3/4 cup. However, this will result in some wastage. Fill the 3/4 cup with your ingredient, then pour half of it into the 1-cup measuring cup. This will give you 1/2 cup of the ingredient, leaving 1/4 cup unused.

2. For 1 3/4 cups: Fill the 1-cup measuring cup to its maximum capacity. Then, fill the 3/4 cup slightly more than halfway. Combine the two by pouring the 1-cup measure into the 3/4 cup. This will give you 1 3/4 cups.

3. For 2 1/4 cups: Fill the 1-cup measuring cup to its maximum capacity. Fill the 3/4 cup slightly more than halfway, then pour it into the 1-cup measure. Now, we have 1 3/4 cups. Add another 1/2 cup to it by filling the 3/4 cup halfway and pouring it into the 1-cup measure. This will give us a total of 2 1/4 cups.

4. For 2 5/2 cups: Here, we can only approximate the measurement using the available cups. One way to measure this is by using the 1-cup measure five times (1 cup x 5 = 5 cups). Then utilize the 3/4 cup to measure an additional 1/2 cup (because 4 x 3/4 = 3 cups). In total, we have 5 cups + 1/2 cup = 5 1/2 cups.

It's important to note that while these methods allow for accurate approximations using the available measuring cups, they may not be as precise as using the exact measurements. Adjustments may be needed depending on the recipe and the required precision.
