Answer: (A)

To understand why the equivalent of 1 gallon is 128 fluid ounces, it’s helpful to know the relationship between these two measurements.

1 gallon is defined as being equal to 128 fluid ounces. This conversion comes from the fact that a gallon is a larger unit of volume commonly used in the United States customary system, while fluid ounces are a smaller unit of measurement. The fluid ounce is typically used for measuring liquid ingredients.

To break it down:

• 1 gallon = 4 quarts

• 1 quart = 32 fluid ounces

Thus, if you multiply:

• 4 quarts/gallon × 32 fluid ounces/quart = 128 fluid ounces/gallon

This established conversion factor shows that any time you need to convert gallons to fluid ounces, you would multiply the number of gallons by 128. Therefore, saying that 1 gallon equals 128 fluid ounces is accurate and reflects the proper conversion between these two measurements.
