Exercise 9 Page 25

To identify the Property of Real Numbers being demonstrated by the given equation, we should first identify the operation being performed. 2.3(3.4* 12.9)=(2.3* 3.4)(12.9) In this case, the terms are being multiplied. The equation shows that changing the grouping of the factors being multiplied does not change the product. This is the Associative Property of Multiplication.

2.3(3.4* 12.9)=(2.3* 3.4)(12.9)
