Final answer:
To find out how many milliliters three buckets would hold, convert 2.5 liters to milliliters by multiplying by 1,000, resulting in 2,500 milliliters per bucket. Multiplying this by 3 gives a total of 7,500 milliliters for three buckets.
Step-by-step explanation:
If one bucket holds 2.5 liters, we first need to find out how many milliliters there are in 2.5 liters. To do this, we know that 1 liter is equivalent to 1,000 milliliters. Therefore, to convert liters to milliliters, you multiply the number of liters by 1,000.
2.5 L × 1,000 = 2,500 milliliters
Since the student needs to find out how many milliliters three buckets would hold, we then multiply 2,500 milliliters by 3.
2,500 mL × 3 = 7,500 milliliters
Therefore, three buckets would hold a total of 7,500 milliliters.
