Question 2.

Jamal used \(\frac{1}{3}\) yard of ribbon to tie a package and \(\frac{1}{6}\) yard of ribbon to tie a bow. How many yards of ribbon did Jamal use?

Answer:

Explanation :

Length of ribbon used to tie package = \(\frac{1}{3}\) yard

Length of ribbon used to tie bow = \(\frac{1}{6}\) yard

Total length of ribbon used by jamal = \(\frac{1}{3}\) + \(\frac{1}{6}\) = \(\frac{2}{6}\) + \(\frac{1}{6}\) = \(\frac{3}{6}\) = \(\frac{1}{2}\) .

Question 3.

Over the weekend, Nolan drank \(\frac{1}{6}\) quart of orange juice, and Andrea drank \(\frac{3}{4}\) quart of orange juice. How many quarts did they drink together?

Answer :

Explanation :

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:

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 1.

\(\frac{1}{2}\) + \(\frac{1}{5}\) =

Answer:

\(\frac{1}{2}\) + \(\frac{1}{5}\) = \(\frac{5}{10}\) + \(\frac{2}{10}\) = \(\frac{7}{10}\)

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 .

Question 2.

Rajesh jogged \(\frac{3}{4}\) mile and then walked \(\frac{1}{6}\) mile to cool down. How far did he travel?

Answer:

Distance traveled by Rajesh by jogging = \(\frac{3}{4}\) mile

Distance traveled by Rajesh by walking = \(\frac{1}{6}\) mile

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:

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 :

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 – \(\frac{17}{30}\) = \(\frac{30 }{30}\) – \(\frac{17}{30}\) = \(\frac{13}{30}\) .
