The Correct answer and Explanation is:
The correct answer is C. 3,900 milliliters.
To understand why, it’s essential to know the relationship between liters and milliliters. The metric system is based on units that are powers of ten, which makes conversions straightforward. Specifically, one liter is equivalent to 1,000 milliliters.
Here’s a step-by-step explanation:
- Conversion Factor: The key to converting liters to milliliters is the conversion factor between these units. One liter (L) equals 1,000 milliliters (mL). This can be represented mathematically as:1 L=1,000 mL1 \text{ L} = 1,000 \text{ mL}1 L=1,000 mL
- Multiplying for Conversion: To find out how many milliliters are in 3.9 liters, you multiply the number of liters by the conversion factor:3.9 L×1,000 mL/L3.9 \text{ L} \times 1,000 \text{ mL/L}3.9 L×1,000 mL/LHere, “L” (liters) cancels out, leaving you with milliliters.
- Calculation: Performing the multiplication:3.9×1,000=3,900 mL3.9 \times 1,000 = 3,900 \text{ mL}3.9×1,000=3,900 mL
- Result: Therefore, 3.9 liters equals 3,900 milliliters.
Understanding this conversion is crucial, especially in fields like nursing, where precise measurements are critical. For example, when administering medications or fluids, nurses often need to convert between liters and milliliters to ensure the correct dosage. This simple conversion can prevent errors and ensure patient safety.
Thus, by converting 3.9 liters to milliliters, we arrive at the correct answer of 3,900 milliliters, confirming that the appropriate choice is C.
