Question 1.

Frank and Dwayne weed their gardens that are the same size. Frankâ€™s garden is divided into 6 equal sections. Dwayneâ€™s garden is divided into 4 equal sections. Each boy has weeded 2 sections of his garden.

Write a fraction to describe what part of his garden each boy has weeded. Then tell who weeded a larger area. Explain

_________

Answer: Dwayneâ€™s part 2/4 > Frankâ€™s part 2/6.

Explanation:

Frank and Dwayne has the same size of gardens

Frankâ€™s garden is divided into 6 equal sections

Dwayneâ€™s garden is divided into 4 equal sections

Since each has weeded 2 sections of their gardens, Frankâ€™s part would be = 2/6,

Dwayneâ€™s part would be = 2/4.

Therefore Dwayneâ€™s part 2/4 > Frankâ€™s part 2/6,

Since the garden with a greater number of sections will have a smaller area per section.

Question 2.

Eli, Beth, and Cory are reading the same book for class. Eli read \(\frac{3}{4}\) of his book. Beth read \(\frac{3}{8}\) of her book and Cory read \(\frac{3}{6}\) of his book. For 2aâ€“2d, choose Yes or No to indicate whether the comparisons are correct.

a. \(\frac{3}{4}\) > \(\frac{3}{8}\)

i. yes

ii. no

Answer: Yes.

Explanation: 3/4 > 3/8. Since both are reading the same book and book with a greater number of sections will have a lesser value.

Question 2.

b. \(\frac{3}{6}\) < \(\frac{3}{8}\)

i. yes

ii. no

Answer: No, 3/6 < 3/8.

Explanation: It’s not true, Since both are reading the same book, and books with a greater number of sections will have a lesser value. Therefore 3/6 > 3/8).

Question 2.

c. \(\frac{3}{8}\) = \(\frac{3}{6}\)

i. yes

ii. no

Answer: No

Explanation: 3/8 = 3/6. Both are not equal, since the same book has been divided into different no of parts. Therefore both are not equal.

Question 2.

d. \(\frac{3}{6}\) < \(\frac{3}{4}\)

i. yes

ii. no

Answer: Yes.

Explanation: 3/6 < 3/4. Since both are reading the same book and book with a greater number of sections will have a lesser value.

Question 4.

MacKenzie and Cassie used fabric to make costumes for a play. MacKenzie used \(\frac{3}{4}\) yard of fabric and Cassie used \(\frac{5}{6}\) yard. Who used more fabric? Explain the strategy you used to solve the problem.

_________

Answer:

MacKenzie divided fabric into 4 equal parts and used 3/4 of it. So, 1/4 of it is left. Cassie divided the same yard of fabric into 6 equal parts and used 5/6 of it. Here 1/6 part of it is left, by comparing leftover pieces we can conclude 1/4 > 1/6. Since the larger piece was left with MacKenzie, Cassie has used more fabric.

Question 12.

Will, Ann, and Jim are working on their science fair projects. Will has finished \(\frac{1}{4}\) of his project. Ann has finished \(\frac{3}{4}\) of her project, and Jim has finished \(\frac{2}{3}\) of his project.

Part A

Who has finished less of their project, Will or Ann?

Explain how you know.

__________

Answer: Will has finished less compared to Ann.

Explanation: Given that will has finished 1/4 of his project wherein Ann has finished 3/4 of her project. Since 1/4 and 3/4 have the same denominator, so we can compare the numerator directly. Since 1 is less than 3, we can say 1/4 is less than 3/4. Thus Will has finished less part of his project compared to Ann.

Question 12.

Part B

Who has finished less of their project, Ann or Jim?

Explain how you know.

__________

Answer: 2/3 is less than 3/4. Therefore, Jim has finished less part of his project compared to Ann.

Explanation: Given that Jim has finished 2/3 of his project were in Ann has finished 3/4 of her project. Since denominators are not the same to compare first we shall make the same. Therefore multiply Jimâ€™s work (2/3) with (4/4) which gives = 8/12 and Annâ€™s work (3/4) with (3/3) which gives = 9/12. Now by comparing numerators 8/12 is less than 9/12, which means Jim has finished less part of his project compared to Ann.

Question 13.

Sarah needs \(\frac{4}{6}\) yard of ribbon to wrap a gift. She has 6 pieces of ribbon with the following lengths. She can cut the piece if it is too long. Mark all of the pieces of ribbon that Sarah could use.

Options:

a. \(\frac{1}{2}\) yard

b. \(\frac{6}{6}\) yard

c. \(\frac{3}{8}\) yard

d. \(\frac{4}{4}\) yard

e. \(\frac{1}{3}\) yard

f. \(\frac{5}{6}\) yard

Answer: Sarah could use 6/6 yard, 4/4 yard and 5/6 yard of ribbons to wrap gift.

Explanation:

Given that Sarah needs a 4/6 yard of ribbon to wrap a gift.

Lengths of available ribbons are 1/2, 6/6, 3/8, 4/4,1/3, and 5/6.

Comparing all the lengths with 4/6 â€“ 6/6 and 5/6 are having the same denominators. So we compare only their numerators, both 6 and 5 are greater than 4. So these two ribbons are more than enough for her gift wrapping. With ribbon length, 4/4 yard â€“ since complete ribbons all the parts of the ribbon are available thus this length also enough to wrap the gift. Remaining 1/2, 3/8, and 1/3 â€“ we shall make their denominators equal to 4/6 to compare

multiply (1/2) with (3/3) = 3/6, 3 is less than 4 in 4/6. So this is not having enough length

multiply (1/3) with (2/2) = 2/6, 2 is also less than 4. So this also not having enough length.

multiply (3/8) with (6/6) = 18/48 and (4/6) with (8/8) = 32/48. Since 18 is less than 32, this ribbon length also won’t be enough to wrap gifts. Thus Sarah could use only 6/6 yard, 4/4 yard, and 5/6 yard of ribbons to wrap the gift.

Question 14.

There are 8 people having breakfast. Each person wants \(\frac{1}{2}\) of an omelet. How many whole omelets are needed? Use the models to show your answer.

_____ omelets

Answer: Total they need 4 omelets.

Explanation:

Total no of having omelets are = 8

Each person need 1/2 of omelette, so for 8 persons = (1/2) * 8 = 4.

Question 15.

Michele mixed \(\frac{3}{4}\) cup of flour with \(\frac{1}{2}\) cup of water to make paste for an art project. Compare the fractions. Choose the symbol that makes the statement true.

\(\frac{3}{4}\) _____ \(\frac{1}{2}\)

Answer: \(\frac{3}{4}\) > \(\frac{1}{2}\).

Explanation:

Let’s make 3/4 and 1/2 denominators the same (1/2) * (2/2) = 2/4.

Since 3 is greater than 2, 3/4 > 1/2.

Question 16.

Kerri drew a model to show equivalent fractions.

Use the model to complete the number sentence.

\(\frac{2}{3}\) = \(\frac{â–ˇ}{â–ˇ}\)

Answer: \(\frac{2}{3}\) = \(\frac{4}{6}\).

Explanation: Here from the model four parts are shaded out of 6, which also equal to \(\frac{2}{3}\) by value.

Question 19.

Elaine brought \(\frac{3}{4}\) pound of potato salad to a picnic. Jake brought \(\frac{2}{3}\) pound of macaroni salad. Who brought more salad? Explain the strategy you used to solve the problem.

Answer: Elaine has brought more Salad compared to Jake.

Explanation:

Elaine has brought \(\frac{3}{4}\) pound of potato salad

Jake brought \(\frac{2}{3}\) pound of macaroni salad

Lets compare both parts by making their denominators same.Therefore multiply (3/4) * (3/3) = (9/12) and (2/3) * (4/4) = (8/12)

Since 8 is less than 9,\(\frac{8}{12}\)Â < \(\frac{9}{12}\).

Which means \(\frac{2}{3}\) < \(\frac{3}{4}\). Thus Elaine has brought more Salad compared to Jake.

Question 20.

It took Mike \(\frac{2}{6}\) hour to clean his room.

What fraction is equivalent to \(\frac{2}{6}\) ?

\(\frac{2}{6}\) = \(\frac{â–ˇ}{â–ˇ}\)

Answer: \(\frac{2}{6}\) = \(\frac{1}{3}\).
