Let’s solve each problem step by step.
The Commutative Property of Multiplication means you can rearrange the numbers in any order — the product (answer) stays the same.
We’ll rewrite each multiplication fact by rearranging the numbers, then calculate the product.
---
a. 4 × 5
Rearranged: 5 × 4
Product: 5 × 4 = 20
---
b. 5 × 5 × 2
Rearranged: 2 × 5 × 5 (or 5 × 2 × 5, etc.)
Product: First, 5 × 5 = 25; then 25 × 2 = 50
Or: 2 × 5 = 10; then 10 × 5 = 50 → Same answer.
---
c. 7 × 2 × 3
Rearranged: 3 × 2 × 7 (or any order)
Product: 2 × 3 = 6; then 6 × 7 = 42
---
d. 7 × 1 × 11
Rearranged: 11 × 7 × 1 (or 1 × 7 × 11, etc.)
Product: Any number times 1 is itself. So 7 × 11 = 77; then 77 × 1 = 77
---
e. 5 × 4 × 3
Rearranged: 3 × 4 × 5
Product: 3 × 4 = 12; then 12 × 5 = 60
---
f. 1 × 2 × 3 × 4
Rearranged: 4 × 3 × 2 × 1 (or any order)
Product: Let’s do 2 × 3 = 6; then 6 × 4 = 24; then 24 × 1 = 24
Or: 1 doesn’t change anything, so just 2 × 3 × 4 = 24
---
g. 5 × 2 × 5 × 2
Rearranged: 2 × 2 × 5 × 5
Product: 2 × 2 = 4; 5 × 5 = 25; then 4 × 25 = 100
Or: Group as (5 × 2) × (5 × 2) = 10 × 10 = 100
---
h. 6 × 2 × 1 × 4
Rearranged: 4 × 2 × 6 × 1
Product: Ignore the 1 for now. 4 × 2 = 8; 8 × 6 = 48; then 48 × 1 = 48
---
i. 3 × 2 × 5 × 2
Rearranged: 2 × 2 × 3 × 5
Product: 2 × 2 = 4; 3 × 5 = 15; then 4 × 15 = 60
Or: 2 × 3 = 6; 2 × 5 = 10; then 6 × 10 = 60
---
Final Answer:
a. 5 × 4 = 20
b. 2 × 5 × 5 = 50
c. 3 × 2 × 7 = 42
d. 11 × 7 × 1 = 77
e. 3 × 4 × 5 = 60
f. 4 × 3 × 2 × 1 = 24
g. 2 × 2 × 5 × 5 = 100
h. 4 × 2 × 6 × 1 = 48
i. 2 × 2 × 3 × 5 = 60
