Answer:

[2] It shows the commutative property over addition

[3] -5/6

[4] A. 6/7 and B. -101/213

[5] Refer to picture below

[6] True, 1/2 *(-2/3*1/4) = (1/2*-2/3)*1/4.

Explanation:

[3] 5/8 × 8/-6

Simplify


(5)/(8)\left(-(4)/(3)\right)


=-(5)/(6)

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

[4] -6/7

Opposite

6/7

x + ( - 6/7 ) = 0

⇒ x = 6/7

Hence additive inverse of - 6/7 is 6/7

101/213

Opposite

-101/213

x + (101/213)=0

⇒ x = -101/213

Hence additive inverse of 101/213 is -101/213

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

[6] Since x = 1/2 , y = -2/3 and z = 1/4

x * (y*z)=(x*y)*z

Substitute:

1/2 *(-2/3*1/4) = (1/2*-2/3)*1/4

-1/12 = - 1/12

TRUE

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
