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
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
[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
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
