Final answer:
To calculate the flour remaining, multiply the amount needed for one batch by the number of batches made, then subtract the result from the original amount of flour. After making 1 1/2 batches using 1 1/2 cups of flour each, one would have 3.75 cups of flour left from the initial 6 cups.
Step-by-step explanation:
To determine how much flour is left after making 1 1/2 batches of a recipe, we need to calculate the amount of flour used for these batches. The recipe calls for 1 1/2 cups of flour for one batch, so for 1 1/2 batches, the calculation would be:
1 1/2 cups per batch × 1 1/2 batches = 2 1/4 cups of flour used.
We can convert 2 1/4 cups to a decimal for easier subtraction from the original 6 cups:
2 1/4 cups = 2.25 cups
Now, subtract the amount used from the initial amount of flour:
6 cups - 2.25 cups = 3.75 cups
Therefore, after making 1 1/2 batches, you would have 3.75 cups of flour left.
