2. For the milliliters you must multiply them by 12 because each milliliter container needs to be multiplied by 12 to have 3 liters, and for half liters, you must multiply the cost by 6 because there are 6 half liters in 3 liters.
3. You can convert the half liters to cost the same as the liters by multiplying them by 2 since 2 halves is 1 entire liter.
4. 1000 milliliters in 1 liter.
Step-by-step explanation:
