Question

verify associative property of addition and associative property of multiplication -2/3 , 5/4 , 7/12.
​

Answer 1

Step-by-step explanation:

associative property of addition

(-2/3+5/4)+7/12 = -2/3+(5/4+7/12)

(-8+15/12)+7/12 = -2/3+(15+7/12)

7/12+7/12= -2/3+22/12

14/12 = -8+22/12

14/12 =14/12

associative property of multiplication

-2/3 ×(5/4×7/12)=(-2/3×5/4)×7/12

-2/3×(35/48) =(-10/12)×7/12

-35/72=-70/144

-35/72= -35/72
