Associative Property of Multiplication

Associative Property of Multiplication

The property that states that the way factors are grouped does not change the product

Example

(2 x 3) x 4 = 2 x (3 x 4)

6 x 4 = 2 x 12 24 = 24

Associative Property of Multiplication

The property that states that the way factors are grouped does not change the product

Example

(2 x 3) x 4 = 2 x (3 x 4)

6 x 4 = 2 x 12 24 = 24

Associative Property of Multiplication

Associative Property of Multiplication

The property that states that the way factors are grouped does not change the product

Example

(2 x 3) x 4 = 2 x (3 x 4)

6 x 4 = 2 x 12 24 = 24

Associative Property of Multiplication

Associative Property of Multiplication

The property that states that the way factors are grouped does not change the product

Example

(2 x 3) x 4 = 2 x (3 x 4)

6 x 4 = 2 x 12 24 = 24

A problem requiring more than one step to solve

Example

The soccer players sold bottles of water to earn money for equipment They charged $225 for each bottle of water They sold 52 bottles on Saturday and 45 bottles on Sunday How much did they earn Step 1

Add to find the total number of bottles sold

52 bottles sold on Saturday

+45 bottles sold on Sunday

97

The players sold 97 bottles of water Step 2

Multiply to find the amount of money earned

$225 price for each bottle

x 97 total number of bottles

$21825

So the players earned $21825

Associative Property of Multiplication

Associative Property of Multiplication

The property that states that the way factors are grouped does not change the product

Example

(2 x 3) x 4 = 2 x (3 x 4)

6 x 4 = 2 x 12 24 = 24
