Sure! Let’s go through each problem and identify which
property of multiplication is being shown. The properties to choose from are:
-
Associative Property: When multiplying three or more numbers, the way you group them doesn’t change the product.
→ (a × b) × c = a × (b × c)
-
Identity Property: Any number multiplied by 1 stays the same.
→ a × 1 = a
-
Distributive Property: Multiplication distributes over addition or subtraction.
→ a × (b + c) = (a × b) + (a × c)
→ a × (b – c) = (a × b) – (a × c)
-
Commutative Property: The order of multiplication doesn’t matter.
→ a × b = b × a

Now let’s solve each one:
---
1) 4 × 1 = 4
→ Multiplying by 1 gives the same number →
Identity
2) (5 × 7) × 4 = 5 × (7 × 4)
→ Grouping changed, but result same →
Associative
3) 10 × 8 = 8 × 10
→ Order switched →
Commutative
4) 6 × 1 = 1 × 6
→ Order switched →
Commutative
*(Note: Also involves identity, but the property shown is commutative since both sides are equal due to order change.)*
5) 4 × (5 + 6) = (4 × 5) + (4 × 6)
→ Multiplication distributed over addition →
Distributive
6) 6 × (0 + 8) = (6 × 0) + (6 × 8)
→ Again, distribution over addition →
Distributive
7) (8 × 3) × 6 = 8 × (3 × 6)
→ Grouping changed →
Associative
8) 7 × (2 × 3) = (7 × 2) × 3
→ Grouping changed →
Associative
9) 8 × 1 = 8
→ Multiplied by 1 →
Identity
10) 1 × 1 = 1
→ 1 × 1 = 1 → still
Identity (since 1 is the multiplicative identity)
11) 9 × 2 = 2 × 9
→ Order switched →
Commutative
12) 2 × 1 = 2
→ Multiplied by 1 →
Identity
13) 2 × (3 × 0) = (2 × 3) × 0
→ Grouping changed →
Associative
*(Note: Even though 0 is involved, the property shown is associative grouping.)*
14) (1 × 10) + (1 × 3) = 1 × (10 + 3)
→ This is distributive property written backwards →
Distributive
15) (10 × 3) + (10 × 0) = 10 × (3 + 0)
→ Again, distributive →
Distributive
16) 9 × 1 = 1 × 9
→ Order switched →
Commutative
17) 3 × 1 = 3
→ Multiplied by 1 →
Identity
18) 5 × 2 = 2 × 5
→ Order switched →
Commutative
19) 1 × (2 × 4) = (1 × 2) × 4
→ Grouping changed →
Associative
*(Also involves identity, but the structure shows associative property.)*
20) (0 × 3) + (0 × 9) = 0 × (3 + 9)
→ Distributive property →
Distributive
