### Eureka Math Grade 3 Module 2 Lesson 9 Problem Set Answer Key

Part 1
a.
Predict whether each container holds less than, more than, or about the same as 1 liter.

b. After measuring, what surprised you? Why?

Part 2

c. Illustrate and describe the process of decomposing 1 liter of water into 10 smaller units.

Explanation:
I decomposed 1liter of water into 10 smaller units by pouring 100 milliliter of water into each cup.Then count each cup by 100ml.I found that 1000ml that is 10 groups of 100ml is equal to 1 liter.
1000ml/10=100ml.

d. Illustrate and describe the process of decomposing Cup K into 10 smaller units.

Explanation:
I decomposed 100ml of water into 10 smaller units by pouring 10milliliter of water into each cup.Then count each cup by 10ml.I found that 100ml that is 10 groups of 10ml is equal to 100ml.
100ml/10=10ml

e. Illustrate and describe the process of decomposing Cup L into 10 smaller units.

Explanation:
I decomposed 10ml of water into 10 smaller units by pouring 1milliliter of water into each cup.Then count each cup by 1ml.I found that 10ml that is 10 groups of 1ml is equal to 1ml.
10ml/10=1ml

f. What is the same about decomposing 1 liter into milliliters and decomposing 1 kilogram into grams?

Decomposing of 1 liter into milliliters and decomposing 1 kilogram into grams will work same.10ml is ten 1ml, 100ml is ten 10ml and 1 liter is ten 100ml.Both kilograms and grams and liters and milliters are same.

g. One liter of water weighs 1 kilogram. How much does 1 milliliter of water weigh? Explain how you know.

Since decomposing 1 liter into milliters is same as decomposing 1 kilogram into grams, we know that 1ml weighs same as 1 gram.
