PROPERTIES OF MULTIPLICATION
Answers with Step-by-step explanation:
1. Using Commutative Property, complete the equation: 9 x 10 = ?.
a. 10 + 9 b. 9 + 10 c. 9x (9+1) d. 10 x 9
Solution:
The Commutative Property of Multiplication states that the order of the factors does not affect their product. So since the given is 9 x 10, switching them as 10 x 9 will still yield the same product which is 90. Thus, the correct answer is on letter D.
2. What property of multiplication is illustrated in 9 * 7 = 7 *9?
a. Identity Property b. Commutative Property c. Distributive Property d. Associative Property
Solution:
The correct answer is letter B. It illustrates the Commutative Property of Multiplication.
3. 2 Using Distributive Property, which of the following completes the multiplication sentence: 2 x (10 + 8) = ?
a. (2 x 10) + (10 x 8) b. (2 x 10) + (10 x 2) c. (2 x 10) + (2 x 8) d. (2 + 10) x (2 + 8)
Solution:
The correct answer is letter C. 2 is distributed to 10 and 8. Still their answer does not change.
4. What property of multiplication is being illustrated: 3 x (9 x 2) = (3 x 9) x 2? a. Identity Property b. Commutative Property c. Distributive Property d. Associative Property
Solution:
The correct answer is letter D. This illustrates the associative property of multiplication which states that the groupings of the factors do not affect their product.
