To convert metric units of volume involving fractions, you essentially follow the same conversion steps but apply fraction arithmetic (multiplication or division) with the conversion factor.
Here's a general approach:
- Identify the conversion factor: Determine how many of the target units are in one of the starting units (e.g., 1 L = 1000 mL).
- Set up the conversion:
- If converting from a larger unit to a smaller unit (e.g., Liters to milliliters), you will multiply by the conversion factor.
- If converting from a smaller unit to a larger unit (e.g., milliliters to Liters), you will divide by the conversion factor (or multiply by its reciprocal).
- Perform fraction arithmetic:
- Convert mixed numbers to improper fractions before multiplying or dividing.
- Multiply fractions: Multiply the numerators and multiply the denominators.
- Divide fractions: Multiply the first fraction by the reciprocal of the second fraction.
- Simplify the resulting fraction if possible.
Example: Convert 43 Liters to milliliters.
- Conversion factor: 1 Liter = 1000 milliliters.
- Set up: We are going from a larger unit (Liters) to a smaller unit (milliliters), so we multiply.
43L×1000LmL
- Perform fraction arithmetic:
43×11000=4×13×1000=43000
- Simplify:
43000=750
So, 43 Liters is equal to 750 milliliters.
