No of persons to work = 4
total no of fields = 3
So dividing 3 equal-sized fields 4 equal parts = ¾
Therefore each person gets ¾ of the field as their share to mow.

Question 8.
Bailey shaded this model.
Select one number from each column to show the part of the model Bailey shaded.
Answer: Numerator – 4, Denominator – 6.
Explanation: Given the model shows 6 equal parts in which Bailey shaded 4 parts. Therefore, the fractional part Bailey shaded is 4/6. From the fraction Numerator is 4, Denominator is 6.
Question 9.
Jayson baked a pan of cornbread for a family dinner. He cut the cornbread into equal size pieces. At the end of the dinner, there were 2 pieces left. Explain how you find the number of pieces in the whole pan of cornbread if Jayson told you that 16 of the pan was left. Use a drawing to show your work.
_____ pieces
Answer: 12 pieces
Explanation:
No of bread pieces left after dinner = 2
Considering 1/6 of the pan was left, we draw 6 ovals since the denominator is 6. Since 2 pieces are 1/6 of the pan, we represent them two circles in each oval. Therefore total no of pieces in the whole pan of cornbread are = 6 × 2 = 12.

Question 10.
The model shows one whole. What fraction of the model is NOT shaded?
\(\frac{□}{□}\)
Answer: \(\frac{3}{4}\) of the model is not shaded.
Explanation: Given model is a circle that is divided into 4 parts. Out of which 1 part is shaded. Thus \(\frac{3}{4}\) of the model is not shaded.
Question 11.
Michael replaced \(\frac{1}{3}\) of the buttons on his coat. If he replaced a total of 3 buttons, how many buttons are on his coat? Show your work.
______ buttons
Answer: 9 buttons.
Explanation:
Let’s consider the total no of buttons be X
Given that Michael replaced 1/3 of his coat buttons which are 3 in number
which means 1/3 × X = 3
therefore X = 3×3 = 9
So the total no of buttons on his coat are 9.
Question 12.
Four teachers share 3 gallons of paint equally. How much paint does each teacher get?
_____ fourths
Answer: ¾
Explanation:
No of teachers to share paint = 4
the total amount of paint = 3 gallons
So dividing 3 gallons of paint into 4 equal parts = ¾
Therefore each teacher gets ¾ of paint as their share.
Question 13.
Each shape is 1 whole.
For numbers 13a–13e, choose Yes or No to show whether the number names the parts that are shaded.
a. 3
i. yes
ii. no
Answer: No
Explanation: The total 4 models are shaded.
Question 13.
b. 4
i. yes
ii. no
Answer: Yes
Explanation: The 4 models are shaded.
Question 13.
c. \(\frac{12}{3}\)
i. yes
ii. no
Answer: Yes
Explanation: \(\frac{12}{3}\) means 4 parts, which represents 4 shaded parts/model.
Question 13.
d. \(\frac{12}{4}\)
i. yes
ii. no
Answer: No
Explanation: \(\frac{12}{4}\) means 3 parts, which represents 3 shaded parts/model. So answer is no.
Question 13.
e. \(\frac{3}{12}\)
i. yes
ii. no
Answer: No.
Explanation: \(\frac{3}{12}\) means \(\frac{1}{4}\) part is shaded. So answer is no.

Question 14.
A store sold 6 fruit trees. Five of the trees were apple trees. What fraction of the trees were apple trees?
\(\frac{□}{□}\)
Answer: \(\frac{5}{6}\)
Explanation:
Given that total of 6 trees were sold
no of apple trees are 5
Therefore fraction of apple trees out of total sold trees are = No of apple trees / Total no of trees
= \(\frac{5}{6}\).
Question 15.
Christina and Erin made vegetable trays for a neighborhood picnic.
Part A
Christina put 15 vegetables on her tray. If \(\frac{1}{5}\) of the vegetables were carrots, how many carrots were on the tray? Make a drawing to show your work.
_____ carrots
Answer: 3 carrots.
Explanation:
Total vegetables on Christina tray = 15
part of carrots on the tray = 1/5
Total of carrots = (Total no of vegetables × part of the carrots)
= 15 × 1/5 = 3 carrots.
Question 15.
Part B
Erin put 20 vegetables on her tray. If \(\frac{1}{4}\) of them were carrots, how many carrots were on Christina’s and Erin’s trays? Explain how you found your answer.
_____ carrots
Answer: Total 8 carrots.
Explanation:
No of carrots in Christina’s tray = 3
Total vegetables on Erin’s tray = 20
part of carrots on the tray = 1/4
Total of carrots = (Total no of vegetables × part of the carrots)
= 20 × 1/4
= 5 carrots.
Therefore total no of carrots on both of their trays = 5 + 3 = 8 carrots
Question 16.
Maria has 8 tulip bulbs. She gives 5 of the tulip bulbs to her neighbor. What fraction of her tulip bulbs does she give to her neighbor?
\(\frac{□}{□}\) tulip bulbs
Answer: \(\frac{5}{8}\)
Explanation:
Total no of tulip bulbs Maria has = 8
No of tuple bulbs she gave to neighbor = 5
Therefore fraction of tuple bulbs she gave =\(\frac{5}{8}\).

Question 17.
Lucy rode her bike around the block 4 times for a total of 1 mile yesterday. Today she wants to ride her bike \(\frac{3}{4}\) of a mile. How many times will she need to ride her bike around the block?
______ times
Answer: 3 times
Explanation:
No of times Lucy rode to complete 1 mile = 4
So in one time, she completes ¼ mile
Therefore to complete ¾ mile, she has to complete = ¼ + ¼ + ¼, which is 3 times
Question 18.
Jackson colored some shapes.
Select one number from each column to show a fraction greater than 1 that names the parts Jackson colored.
Answer: Numerator – 6, Denominator – 2
Explanation: As there are 6 halves that are shaded and the fraction greater than 1 is \(\frac{6}{2}\).
Question 19.
Samira ran around a park loop that was \(\frac{1}{3}\) mile long. She ran around the loop 9 times. Samira says she ran \(\frac{9}{3}\) miles. Her brother Amal says she ran 3 miles. Who is correct? Use words and drawings to explain how you know.
_________
Answer: Both are correct.
Explanation:
The distance of the loop is = \(\frac{1}{3}\) mile
Samira ran around nine times = 9 × \(\frac{1}{3}\)
=\(\frac{9}{3}\)
= 3miles
So both are correct.
Each circle represents a park where each shaded part we considered as 1/3 mile. Each circle can be completed in 3 rounds, therefore running nine times covers all the three circles = 9 ×\(\frac{1}{3}\)
= \(\frac{9}{3}\).
= 3miles.
