Question 1.
The ____ states that the product of any number and 1 is that number.
Answer:
The Identity Property of multiplication states that the product of any number and 1 is that number.
Question 2.
To find (3 × 2) × 4, I can use the ___ to show 3 × (2 × 4) to find the same product.
Answer:
To find (3 × 2) × 4, I can use the Associative Property of multiplication to show 3 × (2 × 4) to find the same product.
Question 3.
To find 9 × 8, I can use the to show 9 × (3 + 5) to find the product.
Answer:
To find 9 × 8, I can use the Distributive Property of Multiplication to show 9 × (3 + 5) to find the product.
Concepts and Skills
Question 4.
Use Tools Match each fact with the product. Tell what strategy or too! you will use to answer the problems, explain your choice, and then find the answers.
Answer:
Explanation:
I matched the product with the facts
6 x 8 =
I use 3’s fact and double the product to solve
3 x 8 = 24
24 + 24 = 48
So, 6 x 8 = 48
(3 x 5) + (3 x 2)=
Add the products
15 + 6 = 21
7 x (6 + 3)
I use distributive property
(7 x 6) + (7 x 3)
= 42 + 21
= 63
So, (7 x 6) + (7 x 3) = 63
(4 + 4) 9 =
I use distributive property
(4 x 9) + (4 x 9)
= 36 + 36
= 72
So, (4 x 9) + (4 x 9) = 72.
Question 5.
Use the multiplication table. Select all the statements that correctly describe how to find the products for the factor 8 in the multiplication table.
A. Find all the products in the same row or the same column as the factor 8.
B. Find all the factors that would meet at the product 8.
C. Add the products for 2 to the products for 6.
D. Find all the numbers that end with 8.
E. Multiply the products for 3 with the products for 5.
Answer:
A. Find all the products in the same row or the same column as the factor 8.
B. Find all the factors that would meet at the product 8.
C. Add the products for 2 to the products for 6.
Explanation:
The above statements are correct about the factors of 8
All the products in the same row or the same column of factor 8 are multiples of 8
The factors that would meet at 8 are multiples of 8
The sum of the products for 2 and products for 6 are multiples of 8.
Question 6.
Which is the unknown number in the shown equation?
(3 × 2) × 5 = 3 × (
× 5)
A. 21
B. 14
C. 3
D. 2
Answer:
D. 2
Explanation:
Commutative property of multiplication states that we can change the order of the numbers to find the product
So, the unknown number is 2.
Question 7.
Make an equation that is true.
9 × 6 = (
+ ) × ___________
Answer:
9 x 6 = (5 + 4) x 6
Explanation:
Use distributive property of multiplication
Break part the fact to make the equation true
So, 9 = 5 + 4
Therefore, the number 5 and 4 make the equation true.
Question 8.
Julia says that if you multiply 4 by an even number or an odd number, the product is always even. Is Julia correct? Explain.
Answer:
Yes, Julia is correct
Explanation:
Julia says that if you multiply 4 by an even number or an odd number, the product is always even
The multiple of even number will always be even
So, all multiples of 4 are even numbers.
