Quantity of Orange juice drank by Nolan= \(\frac{1}{6}\) quart
Quantity of Orange juice drank by Andrea = \(\frac{3}{4}\) quart
Total Quantity of orange juice drank by both of them = \(\frac{1}{6}\) + \(\frac{3}{4}\) = \(\frac{2}{12}\) \(\frac{9}{12}\) = \(\frac{11}{12}\) quarts .

Question 4.
Nadia spent \(\frac{1}{4}\) of her money on a shirt and \(\frac{2}{5}\) of her money on new shoes. What fraction of Nadia’s money has been spent? What fraction of her money is left?
Answer:
Eureka Math Grade 5 Module 3 Lesson 3 Answer Key (11)
consider total money = 1 whole .
Money spent on shirt = \(\frac{1}{4}\)
Money spent on new shoes = \(\frac{2}{5}\)
Total Money spent on Nadia = \(\frac{1}{4}\) + \(\frac{2}{5}\) = \(\frac{5}{20}\) + \(\frac{8}{20}\) = \(\frac{13}{20}\)
Fraction of money left = 1 – \(\frac{13}{20}\) = \(\frac{20}{20}\) – \(\frac{13}{20}\) = \(\frac{7}{20}\) .

Question 2.
In one hour, Ed used \(\frac{2}{5}\) of the time to complete his homework and \(\frac{1}{4}\) of the time to check his email. How much time did he spend completing homework and checking email? Write your answer as a fraction. (Extension: Write the answer in minutes.)
Answer:
Time used by Ed to complete his home work = \(\frac{2}{5}\)
Time used by Ed to check his email = \(\frac{1}{4}\)
Total Time Spent by Ed = \(\frac{2}{5}\) + \(\frac{1}{4}\) = \(\frac{8}{20}\) +\(\frac{5}{20}\) = \(\frac{13}{20}\) .
1 hour = \(\frac{20}{20}\) = \(\frac{60}{60}\) multiplied by 3
\(\frac{13}{20}\) = \(\frac{39}{60}\) that means 39 minutes .

Rajesh jogged \(\frac{3}{4}\) mile and then walked \(\frac{1}{6}\) mile to cool down. How far did he travel?
Answer:
Eureka Math Grade 5 Module 3 Lesson 3 Answer Key (19)
Distance traveled by Rajesh by jogging = \(\frac{3}{4}\) mile
Distance traveled by Rajesh by walking = \(\frac{1}{6}\) mile
Total Distance traveled by Rajesh = \(\frac{3}{4}\) + \(\frac{1}{6}\) = \(\frac{9}{12}\) + \(\frac{2}{12}\) = \(\frac{11}{12}\)

Question 3.
Cynthia completed \(\frac{2}{3}\) of the items on her to-do list in the morning and finished \(\frac{1}{8}\) of the items during her lunch break. What fraction of her to-do list is finished by the end of her lunch break? (Extension: What fraction of her to-do list does she still have to do after lunch?)
Answer:
Eureka Math Grade 5 Module 3 Lesson 3 Answer Key (20)
Work done by Cynthia in the morning = \(\frac{2}{3}\)
Work done by Cynthia in the lunch break = \(\frac{1}{8}\)
Total work done = \(\frac{2}{3}\) + \(\frac{1}{8}\) = \(\frac{16}{24}\) + \(\frac{3}{24}\) = \(\frac{19}{24}\).

Question 4.
Sam read \(\frac{2}{5}\) of her book over the weekend and \(\frac{1}{6}\) of it on Monday. What fraction of the book has she read? What fraction of the book is left?
Answer :
Eureka Math Grade 5 Module 3 Lesson 3 Answer Key (21)
Fraction of her book read by weekend = \(\frac{2}{5}\)
Fraction of her read by Monday = \(\frac{1}{6}\)
Fraction of book read = \(\frac{2}{5}\) + \(\frac{1}{6}\) = \(\frac{12}{30}\) + \(\frac{5}{30}\) = \(\frac{17}{30}\)
Fraction of book left to read = 1 – \(\frac{17}{30}\) = \(\frac{30 }{30}\) – \(\frac{17}{30}\) = \(\frac{13}{30}\) .
