Exercise 2:
Making Juice (Comparing Juice to Water)

a. The tables below show the comparison of the amount of water to the amount of juice concentrate (JC) in grape juice made by three different people. Whose juice has the greatest water-to-juice concentrate ratio, and whose juice would taste strongest? Be sure to justify your answer.
Answer:
Franca’s juice has the greatest amount of water in comparison to juice concentrate, followed by Milton, and then Laredo, Because Laredo’s juice has the least amount of water in comparison to juice concentrate, his juice would taste the strongest.

Answer:
Eureka Math Grade 6 Module 1 Lesson 11 Exercise Answer Key 7

Put the juices in order from the juice containing the most water to the juice containing the least water.
Answer:
Franca, Milton, Laredo

Explain how you used the values in the table to determine the order.
Answer:
Laredo makes his juice by combining three cups of water for every one cup of juice concentrate.
Franca makes her juice by combining five cups of water for every one cup of juice concentrate.
Milton makes his juice by combining four cups of water for every one cup of juice concentrate.

What ratio was used to create each table?
Answer:
Laredo 3: 1, Franca 5: 1, Milton 4: 1

Explain how the ratio could help you compare the juices.
Answer:
Answers will vary.

b. The next day, each of the three people made juice again, but this time they were making apple juice. Whose juice has the greatest water-to-juice concentrate ratio, and whose juice would taste the strongest? Be sure to justify your answer.

Answer:
Answers will vary.

c. Max and Sheila are making orange juice. Max has mixed 15 cups of water with 4 cups of juice concentrate. Sheila has made her juice by mixing 8 cups water with 3 cups of juice concentrate. Compare the ratios of juice concentrate to water using ratio tables. State which beverage has a higher juice concentrate-to-water ratio.
Answer:
Eureka Math Grade 6 Module 1 Lesson 11 Exercise Answer Key 10
Sheila has a higher juice concentrate-to-water ratio because she mixed 12 cups of juice concentrate to only 32 cups of water. Max’s juice would be more watery because he would have 45 cups of water with the 12 cups of juice concentrate.

d. Victor is making recipes for smoothies. His first recipe calls for 2 cups of strawberries and 7 cups of other ingredients. His second recipe says that 3 cups of strawberries are combined with 9 cups of other Ingredients. Which smoothie recipe has more strawberries compared to other ingredients? Use ratio tables to justify your answer.
Answer:
Recipe 2 has more strawberries compared to other ingredients.
Eureka Math Grade 6 Module 1 Lesson 11 Exercise Answer Key 11
Recipe 2 has more strawberries compared to the other ingredients. When comparing 6 cups of strawberries, there were fewer other ingredients added in Recipe 2 than in Recipe 1.

Question 1.
Beekeepers sometimes supplement the diet of honey bees with sugar water to help promote colony growth in the spring and help the bees survive through fall and winter months. The tables below show the amount of water and the amount of sugar used in the Spring and in the Fall.
Eureka Math Grade 6 Module 1 Lesson 11 Exit Ticket Answer Key 14

Write a sentence that compares the ratios of the number of cups of sugar to the number of cups of water in each table.
Answer:
The value of the ratio for the Spring sugar water is \(\frac{1.5}{1}\), while the value of the ratio of the Fall sugar water is \(\frac{2}{1}\). Therefore, the Fall sugar water mixture has more sugar mixed in for every cup of water added to the mixture than the Spring sugar water mixture.

Explain how you determined your answer.
Answer:
Spring: \(\frac{6}{4}\) = \(\frac{3}{2}\) = \(\frac{1.5}{1}\)
Fall: \(\frac{4}{2}\) = \(\frac{2}{1}\)
