• I will convert metric units of capacity. • liter • milliliter

Convert Larger Units to Smaller Units As part of a science experiment, a plant was given three liters of water each week for twelve weeks. How many milliliters of water were given to the plant in all? 3 L= m. L A liter is larger than a milliliter, so multiply. 3 × 1, 000 = 3, 000 1 L = 1, 000 m. L, so multiply 3 by 1, 000. 3 L = 3, 000 m. L × 12 = 36, 000 m. L Multiply 3, 000 m. L by 12 weeks.

Convert Larger Units to Smaller Units Answer: So, 3 L = 3, 000 m. L. In 12 weeks, 3, 000 × 12 or 36, 000 m. L of water were given to the plant in all.

Convert 17 liters to milliliters. A. 170 m. L B. 1, 700 m. L C. 17, 000 m. L D. 170, 000 m. L 1. 2. 3. 4. A B C D

Model an Array How many liters is 850 milliliters? Estimate 850 m. L < 1, 000 m. L, so the number of liters is less than 1. 850 m. L = L THINK 850 m. L is what part of 1, 000 m. L? 850 m. L = 1, 000 L or 0. 85 L Write 850 as a decimal. 1, 000 Answer: So, 850 m. L = 0. 85 L.

How many liters is 121 milliliters? A. 121 L B. 12. 1 L C. 1. 21 L D. 0. 121 L 1. 2. 3. 4. A B C D

Model an Array The Jackson family bought two cases of bottled water. Each case has 28 bottles with 250 m. L of water in each bottle. Find the total number of liters in the two cases. First, find the total number of milliliters in one case. 28 × 250 = 7, 000 Multiply.

Model an Array There are 2 cases, so multiply 7, 000 by 2 to find the total number of milliliters in both cases. 7, 000 × 2 = 14, 000 Multiply. Next, convert 14, 000 milliliters to liters. 14, 000 ÷ 1, 000 = 14 1, 000 m. L = 1 L, so divide 14, 000 by 1, 000. Answer: So, 14, 000 m. L = 14 L. The total amount of water in the two cases is 14 liters.

Jude bought 3 cases of soda. Each case has 24 cans with 500 m. L of soda in each can. Find the total number of liters in the two cases. A. 3. 6 L B. 36 L C. 360 L D. 3, 600 L 1. 2. 3. 4. A B C D
