Here's the solution with explanations for each multiplication property:
---
Key:
-
CPM = Commutative Property of Multiplication
→ *Order doesn’t matter*: `a × b = b × a`
-
APM = Associative Property of Multiplication
→ *Grouping doesn’t matter*: `(a × b) × c = a × (b × c)`
-
ZPM = Zero Property of Multiplication
→ *Any number × 0 = 0*: `a × 0 = 0`
-
IPM = Identity Property of Multiplication
→ *Any number × 1 = itself*: `a × 1 = a`
---
Solutions:
1.
2 × 3 = 3 × 2 →
CPM
→ The order of the numbers is switched, but the product is the same.
2.
0 × 7 = 0 →
ZPM
→ Any number multiplied by zero equals zero.
3.
1 × 6 = 6 →
IPM
→ Multiplying by 1 leaves the number unchanged.
4.
2 × (4 × 5) = (2 × 4) × 5 →
APM
→ The grouping of numbers changes, but the result is the same.
5.
8 × 5 = 5 × 8 →
CPM
→ Order of factors is reversed — commutative property.
6.
(9 × 2) × 4 = 9 × (2 × 4) →
APM
→ Grouping changes from `(9×2)` first to `(2×4)` first — associative.
7.
12 × 0 = 0 →
ZPM
→ Any number times zero is zero.
8.
37 × 1 = 37 →
IPM
→ Multiplying by 1 gives the original number.
9.
2 × 7 = 7 × 2 →
CPM
→ Switching the order of multiplication — commutative.
10.
5 × (2 × 3) = (5 × 2) × 3 →
APM
→ Changing the grouping of multiplication — associative.
