Answer:
To simplify the expression 1/6 - 8 + 3 - 5/6 + 9, we can use the associative and commutative properties to rearrange the terms. Let's group the terms with addition and subtraction separately:
(1/6 - 5/6) + (-8 + 3 + 9)
Using the commutative property, we can rearrange the terms within each group:
(-5/6 + 1/6) + (9 + 3 - 8)
Now, we can simplify within each group:
(-4/6) + (4)
Finally, we can simplify further:
-2/3 + 4
And that gives us the simplified expression.
