Question 1.
The dance company wants to rent trunks to hold their costumes when they travel. Each trunk can hold costumes for 6 dancers. Which equation could be used to find how many trunks are needed for 48 dancers?
Options:
a. 6 × 48 = ■
b. 48 × ■ = 6
c. 48 × 6 = ■
d. ■ × 6 = 48

Answer: option d, 8 × 6 = 48

Explanation:
Given that trunk can hold costumes for 6 dancers
No of trunks needed to hold costumes of 48 dancers = 48 / 6 = 8
Therefore  8 × 6 = 48.

Question 2.
Select the equations that show the Distributive Property. Mark all that apply.
Options:
a. 3 × 60 = 3 × (20 + 20 + 20)
b. 5 × 20 = (5 × 2) × (5 × 10)
c. 50 × 7 = 7 × 50
d. 8 × (10 + 30) = 8 × 40

Explanation:
Both option a and d shows the Distributive Property,
3 × 60 = 3 × (20 + 20 + 20)
90 = 3 × (60) => 90, LHS = RHS. Same applies for option d as well.

Question 3.
Choose the number from the box that makes the sentence true.

Question 4.
For numbers 4a-4d, choose True or False for each equation.
a. 9 × (3 + 3) = 9 × 6
i. True
ii. False

Explanation: 9 × (3 + 3) = 9 × 6 => 9 × 6 = 54, both L.H.S and R.H.S gives 54.

Question 4.
b. 9 × (4 + 4) = 9 × 6
i. True
ii. False

Explanation: 9 × (4 + 4) = 9 × 6 => 9 × 8 = 9 × 6 => 72 ≠ 54.

Question 4.
c. (3 × 9) + (2 × 9) = 9 × 6
i. True
ii. False

Explanation: (3 × 9) + (2 × 9) = 9 × 6 => 27 + 18 = 9 × 6 => 45 ≠ 54.

Question 4.
d. (9 × 4) + (9 × 2) = 9 × 6
i. True
ii. False

Explanation: (9 × 4) + (9 × 2) = 9 × 6 => 36 + 18 = 54 => 54 = 54, both L.H.S = R.H.S.

Question 5.

Question 8.
Neil made this multiplication model. Complete the equation that represents the model.
_____ × _____ = _____ Answer: 20 × 4 = 80

Explanation:
In the given model every column contains 10 boxes in each row.
Every part has 2 rows, so each part contains 20 boxes
Since we have 4 parts of it total boxes would be = 20 × 4 = 80
Therefore equation that represents the multiplication model is 20 × 4 = 80.

Question 9.
A flower shop delivers fresh flower bouquets to hotels each week. Which hotel buys the least number of flowers? __________

Explanation:
No of flowers in 1 Bouquet of Welcome Inn Hotel = 7
No of Bouquets = 50, total no of flowers = 7 × 50 = 350
No of flowers in 1 Bouquet of Wild Rose Hotel = 8
No of Bouquets = 60, total no of flowers = 8 × 60 = 480
No of flowers in 1 Bouquet of Bayside Hotel = 6
No of Bouquets = 70, total no of flowers = 6 × 70 = 420
No of flowers in 1 Bouquet of Bayside Hotel = 5
No of Bouquets = 80, total no of flowers = 6 × 80 = 480
Therefore comparing all the hotels, Welcome Inn Hotel buys the least number of flowers.

Question 10.
A store has 3 crates of oranges. Each crate holds 2 boxes. Each box holds 20 oranges. What is the total number of oranges in the store?
_____ oranges

Answer: Total no of oranges in the store is 120.

Explanation:
Given that store has 3 crates of oranges having 2 boxes each
Each box holds 20 oranges, total no of oranges = 3 × 2 × 20 = 120.

Question 12.
Shelly describes a pattern. She says the pattern shown in the table is “Add 5.” Is Shelly correct? Explain how you know. _____

Answer: No, she is not correct

Explanation: The pattern works for the first pair of (packages and markers) numbers, not for the remaining. The pattern is “Multiply the number of packages by 6.”

Question 13.
This shows a part of a multiplication table. Find the missing numbers. Explain how you found the numbers.  Explanation:
The only numbers that have a product of 28 are 4 and 7.
The only numbers that have a product of 32 are 4 and 8.
This tells us that 4 is the number for the top row. That means 5 is the next row down and 6 is the row after that.
The factors of the columns are 7 and 8, so we can multiply to find the missing numbers.

Question 14.
Describe a pattern for this table. Pattern: _________________

Answer: Multiply the number of CDs by 50.

How would the table change if the pattern was “Multiply the number of CDs by 5”? Explain.

Answer: The table would change by taking a zero off each number of minutes in the second row because you would be multiplying by ones, not tens.

Question 15.
Aroon has 180 cat toys to pack in boxes. He packs 30 toys in each box. How many boxes does he need?
Write an equation using the letter n to stand for the unknown factor. Explain how to find the unknown factor.

Explanation:
Aroon has 180 cat toys, he packs 30 toys in each box
Let no of boxes needed be n
therefore n × 30 = 180 => n = 180/30 = 6.

Question 16.
A store has 5 shelves of soup. There are 20 cans of soup on each shelf. How many cans of soup does the store have?
Shade squares to make a diagram to show how you can use the Distributive Property to find the number of cans of soup in the store. _____ cans of soup

Answer: 5 × (10 + 10) = (5 × 10) + (5 × 10) = 50 + 50 = 100

Explanation:
Given that store has 5 shelves of Soup, each shelf has 20 cans of soup.
Therefore the number of can of soup store have = 5 × 20 = 100 cans
From the given model we can write 5 × (10 + 10) = (5 × 10) + (5 × 10) = 100. ### Test – Page 6 – Page No. 56
