Step-by-step solution for: Commutative, Associative or Distributive? | 3rd Grade Math
Since I can't view or access images directly, I can't see the specific problems in your uploaded image. However, based on the text you've provided, it looks like the task is to identify whether each given equation demonstrates the Commutative, Associative, or Distributive Property.
Let me help you solve this step by step using the equations listed in your description:
---
- Commutative Property: Order of numbers doesn't matter.
- Addition: $ a + b = b + a $
- Multiplication: $ a \times b = b \times a $
- Associative Property: Grouping of numbers doesn’t matter.
- Addition: $ (a + b) + c = a + (b + c) $
- Multiplication: $ (a \times b) \times c = a \times (b \times c) $
- Distributive Property: Multiplication distributes over addition.
- $ a(b + c) = ab + ac $
---
Now, let's analyze each problem:
---
1. $ 3x + (7x + 2) = (3x + 7x) + 2 $
- The parentheses are moved from around $ (7x + 2) $ to $ (3x + 7x) $ — grouping changed.
- This is Associative Property of Addition.
✔ Answer: Associative
---
2. $ 7(8 + 2) = (8 + 2)(7) $
- Left side: $ 7(8 + 2) $
- Right side: $ (8 + 2)(7) $
- This is just switching the order of multiplication: $ 7 \times (8+2) = (8+2) \times 7 $
- This is Commutative Property of Multiplication.
✔ Answer: Commutative
---
3. $ 4(6 + 6) = 4(6) + 4(6) $
- Multiplying 4 across the sum inside the parentheses: $ 4 \times (6 + 6) = 4 \times 6 + 4 \times 6 $
- This is Distributive Property.
✔ Answer: Distributive
---
4. $ 2(5 + 1) = (2 \times 5) + (2 \times 1) $
- Again, multiplying 2 across the sum: $ 2(5 + 1) = 2 \times 5 + 2 \times 1 $
- This is Distributive Property.
✔ Answer: Distributive
---
5. $ 9 + (24) = (24) + 9 $
- Changing the order of addition: $ 9 + 24 = 24 + 9 $
- This is Commutative Property of Addition.
✔ Answer: Commutative
---
6. $ (8 + 2) + 1 = 8 + (2 + 1) $
- Grouping changed: $ (8 + 2) + 1 $ vs $ 8 + (2 + 1) $
- This is Associative Property of Addition.
✔ Answer: Associative
---
7. $ (6 \times 10) + (6 \times 1) = 6(10 + 1) $
- Left: $ 6 \times 10 + 6 \times 1 $
- Right: $ 6(10 + 1) $
- This is factoring out the common factor 6 — reverse of distribution.
- Still falls under Distributive Property (factoring is the reverse of distributing).
✔ Answer: Distributive
---
8. $ (3 \times 7) + (3 \times 6) = 3 \times (7 + 6) $
- Left: $ 3 \times 7 + 3 \times 6 $
- Right: $ 3(7 + 6) $
- Factoring out the 3 — again, Distributive Property.
✔ Answer: Distributive
---
9. $ (6 \times 7) + (6 \times 10) = 6(7 + 10) $
- Same as above: factoring out 6 from both terms.
- This is Distributive Property.
✔ Answer: Distributive
---
1. Associative
2. Commutative
3. Distributive
4. Distributive
5. Commutative
6. Associative
7. Distributive
8. Distributive
9. Distributive

🔹 Properties Recap:
- Commutative Property: Order of numbers doesn't matter.
- Addition: $ a + b = b + a $
- Multiplication: $ a \times b = b \times a $
- Associative Property: Grouping of numbers doesn’t matter.
- Addition: $ (a + b) + c = a + (b + c) $
- Multiplication: $ (a \times b) \times c = a \times (b \times c) $
- Distributive Property: Multiplication distributes over addition.
- $ a(b + c) = ab + ac $

2. $ 7(8 + 2) = (8 + 2)(7) $
- Left side: $ 7(8 + 2) $
- Right side: $ (8 + 2)(7) $
- This is just switching the order of multiplication: $ 7 \times (8+2) = (8+2) \times 7 $
- This is Commutative Property of Multiplication.
✔ Answer: Commutative
---
3. $ 4(6 + 6) = 4(6) + 4(6) $
- Multiplying 4 across the sum inside the parentheses: $ 4 \times (6 + 6) = 4 \times 6 + 4 \times 6 $
- This is Distributive Property.
✔ Answer: Distributive
---
4. $ 2(5 + 1) = (2 \times 5) + (2 \times 1) $
- Again, multiplying 2 across the sum: $ 2(5 + 1) = 2 \times 5 + 2 \times 1 $
- This is Distributive Property.
✔ Answer: Distributive
---
5. $ 9 + (24) = (24) + 9 $
