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?
Answer:

1 quarts = 2 pints

So, 3 quarts = 3 x 2 = 6

Therefore, Susie has 3 pints

Question 2.

Answer:

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?
Answer:

1 litre = 1,000 millilitres

4 litres = 4 x 1000 = 4000 millilitres

Therefore, Leonard has 4000 millilitres of juice.

Question 4.

15 pints > 1 gallon 1 cup.

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?
Answer:

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?
Answer:

1 gallon = 16 cups

Question 1.
Complete the table.

Answer:

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.
Answer:

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

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?
Answer:

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?
Answer:

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?
Answer:

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 6.
Explain how you solved Problem 5(f).
Answer:

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.

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
