Question

which mathematical property is demonstrated 7+9+3=7+3+91.Associative property of addition 2. Associative property of multiplication 3. commutative property of addition 4. commutative property of multiplication

Answer 1

The equation 7 + 9 + 3 = 7 + 3 + 91 demonstrates the commutative property of addition.

Step-by-step explanation:

Associative Property of Addition: This property deals with grouping numbers during addition. The equation involves only addition and does not demonstrate the associative property because the grouping of numbers is not changing.

Associative Property of Multiplication: This property is not applicable in this case, as the equation involves only addition.

Commutative Property of Addition: This is the correct choice. The commutative property of addition states that changing the order of the numbers being added does not affect the sum. In this case, swapping the positions of 9 and 3 on one side of the equation doesn't change the overall sum.

Commutative Property of Multiplication: This property is not applicable as the equation involves only addition.

So, the correct answer is 3. Commutative Property of Addition.

Answer 2

Mathematical properties

In the case

7 + 9 + 3 = 7 + 3 + 9

we can see this is an addition, then just option 1 and 3 can be true.

In this case we have no grouped numbers but we have that their order was changed.

The associative property refers to grouped numbers and the commutative property refers to the change of order of the terms of the sum, then

Answer: 3. commutative property of addition
