### Eureka Math Grade 4 Module 7 Lesson 2 Problem Set Answer Key

Use RDW to solve Problems 1–3.

Question 1.
Susie has 3 quarts of milk. How many pints does she have?
1 quarts = 2 pints
So, 3 quarts = 3 x 2 = 6
Therefore, Susie has 3 pints

Question 2.
Kristin has 3 gallons 2 quarts of water. Alana needs the same amount of water but only has 8 quarts. How many more quarts of water does Alana need?
Given that, Kristin has 3 gallon 2 quarts of water
1 gallon = 4 quarts
3 gallons 2 quarts = 14 quarts
Also given, Alana needs same amount of water but only has 8 quarts
So, 14 quarts – 8 quarts = 6 quarts
Therefore, Alana needs 6 more quarts.

Question 3.
Leonard bought 4 liters of orange juice. How many milliliters of juice does he have?
1 litre = 1,000 millilitres
4 litres = 4 x 1000 = 4000 millilitres
Therefore, Leonard has 4000 milliliters of juice.

Question 4.

Question 7.
Russell has 5 liters of a certain medicine. If it takes 2 milliliters to make 1 dose, how many doses can he make? Answer:

Total number of litres = 5 litres
1 litre = 1,000 millilitres
5 litres = 1000 x 5 = 5000
Given, 2 millilitres will make 1 dose
5000 / 2 = 2500 ml
Therefore, Russel can make 2500 doses

Question 8.
Each month, the Moore family drinks 16 gallons of milk and the Siler family goes through 44 quarts of milk. Which family drinks more milk each month?
1 gallon = 4 quarts
Given, Moore family drink 16 gallons of milk
So, 16 gallons = 64 quarts
Siler family drinks 44 quarts of milk
Now, 64 – 44 = 20
Therefore, Moore family drinks more milk than Siler family.
Moore family drinks 20 quarts more than Siler.

Question 9.
Keith’s lemonade stand served lemonade in glasses with a capacity of 1 cup. If he had 9 gallons of lemonade, how many cups could he sell?
1 gallon = 16 cups
Now, 9 gallons =
16 x 9 = 144 cups
Therefore, Keith can sold 144 cups of lemonade.

Question 1.
Complete the table.

 Quarts Cups 1 4 2 8 4 16

Question 2.
Bonnie’s doctor recommended that she drink 2 cups of milk per day. If she buys 3 quarts of milk, will it be enough milk to last 1 week? Explain how you know.
Given, Bonnie’s is recommended to drink 2 cups of milk
The amount of milk she bought = 3 quarts
1 quart = 4 cups
So, 3 quarts = 3 x 4 = 12 cups
1 week = 7 days
7 days x 2 cups = 14 cups
14 cups – 12 cups = 2 cups
Therefore,  Bonnie do not have mil to drink for 1 week . there is a shortage of 2 cups.

### Eureka Math Grade 4 Module 7 Lesson 2 Homework Answer Key

Use the RDW process to solve Problems 1–3.
Question 1.
Dawn needs to pour 3 gallons of water into her fish tank. She only has a 1-cup measuring cup. How many cups of water should she put in the tank?
Total quantity of water Dawn needs to pour in fish tank = 3 gallons
We know that,
1 gallon = 16 cups
3 gallons = 16 x 3 = 48
Therefore, Dawn should put 48 cups of water in to the tank.

Question 2.
Julia has 4 gallons 2 quarts of water. Ally needs the same amount of water but only has 12 quarts. How much more water does Ally need?
Given that,
The amount of water Julia has = 4 gallons 2 quarts
The amount of water Ally have = 12 quarts
12 quarts = 3 gallons
Now, 3 gallons – 4 gallons 2 quarts = 1 gallon  2 quarts
Therefore, Ally needs 1 gallon 2 quarts.

Question 3.
Sean drank 2 liters of water today, which was 280 milliliters more than he drank yesterday. How much water did he drink yesterday?
Given,
The amount of water Sean drink today = 2 litres
1 litre = 1000 millilitres
2 litres = 1000 x 2 = 2000 millilitres
Also given, she drank 280 millilitres more than yesterday
Now, 2000 – 280 = 1720
Therefore, the amount of water she drank yesterday = 1720 millilitres.

Question 4.
Complete the tables.
a.

 Gallons Quarts 1 4 2 8 4 16 12 48 15 60

b. 12 gallons 2 quarts = 50 quarts
c. 5 quarts 1 pint = 11 pints
d. 13 quarts 3 pints = 58 cups
e. 17 gallons 2 quarts = 140 pints
f. 27 gallons 3 quarts = 444 cups

Question 6.
Explain how you solved Problem 5(f).
27 gallons 3 quarts = 444 cups
1 gallon = 4 quarts
27 gallons = 27 x 4 = 108 quarts
108 + 3 = 111
1 quart = 4 cups
111 cups = 111 x 4 = 444
Therefore, 27 gallons 3 quarts = 444 Cups.

Question 7.
Answer true or false for the following statements. If your answer is false, make the statement true by correcting the right side of the comparison.
a. 2 quarts > 10 pints __________
b. 6 liters = 6,000 milliliters __________
c. 16 cups < 4 quarts 1 cup ___________

a. 2 quarts > 10 pints __________
False, 1 quart = 2 pints
So, 2 quarts = 4 pints
Therefore, 2 quarts < 10 pints
b. 6 liters = 6,000 milliliters __________

True.
c. 16 cups < 4 quarts 1 cup ___________
False,
1 quart = 4 cups
4 quarts = 4 x 4 = 16 cups
Therefore, 16 cups = 4 quarts.
