Question: How many milliliters of vinegar does she need?

Carlo walks 7.5 kilometers each day. If 1 kilometer equals 1000 meters, how many meters will he walk in 7 days?

A laboratory needs to fill eyedroppers with water. Each drop holds 0.05 mL of water. If the lab has 1.25 liters of water, and 1 liter is equal to 1000 milliliters, how many drops can they produce?

A biology student needs to record the mass of 3 petri dishes. Their masses are 0.45 kg, 500 g, and 1200 g. She must report the total mass in kilograms.

Question: What is the total mass of the petri dishes in kilograms?

Ana needs 3.5 liters of vinegar for her science experiment. Her measuring cup is marked in milliliters, and she can only fill 500 mL at a time. 1 liter is equivalent 1000 mL.

Question:

a. How many milliliters of vinegar does Ana need in total?

b. How many times should she fill the 500 mL cup to reach 3.5 liters?

A student measured 100 mL of water three times and got 100 mL each time.
