each week Julie spends 7 hours reading, 6 hours watching television, and 4 hours playing outside. Use the Associative Property of Addition to write two equivalent expressions that show the total number of hours Julie spends, reading, watching television, and playing outside.

7 hours reading each week

6 hours of watching tv each week

4 hours of playing outside each week

The associative property of addititon is (a+b)+c=a+(b+c)

let 7 = a

let 6 = b

let 4 = c

so you have (7+6)+4=7+(6+4)

the two expressions are (7+6)+4 and 7+(6+4) wink
