Final answer:
To convert from milliliters (mL) to liters (L), divide by 1000. Sean drinks 2.45 liters of milk in a week.
Step-by-step explanation:
To convert from milliliters (mL) to liters (L), you divide by 1000 since there are 1000 milliliters in a liter. So, to find out how many liters of milk Sean drinks in a week, you need to multiply 350 mL by 7 (the number of days in a week) and then divide by 1000.
350 mL × 7 = 2450 mL
2450 mL ÷ 1000 = 2.45 L
