Lesson List


 

The "Associative Property of Multiplication" means grouping factors in any order will not change the product.

 

(10 X 4) X 3 = 120 and 3 X (4 X 10) = 120,

So (3 X 4) X 10 = 3 X (4 X 10)

 

Complete the following:

 

(3 X ) X 15 = 3 X (6 X 15)

( X ) X 12 = 5 X (8 X 12)

(9 X 14) X 3 = X (14 X )

X (50 X 9) = (2 X ) X 9
