Question

Use the associative property to write an equivalent expression for -5/6 • (12•87) and then simplify.

Answer 1

Explanation:

The associative property for multiplication: (a · b) · c = a · (b · c)

`-(5)/(6)\cdot(12\cdot87)=\left(-(5)/(6\!\!\!\!\diagup_1)\cdot12\!\!\!\!\!\diagup^2\right)\cdot87=(-5\cdot2)\cdot87=(-10)(87)=-870`
