Answer:

The simplified expression is -13/12. (are you sure you don't have a typo somewhere), double checked.

Explanation:

First, let's simplify the expression inside the absolute value bars:

5/6 - 17/12 = 10/12 - 17/12 = -7/12

Next, we can simplify the expression outside the absolute value bars:

| -7/12 | - | 5/3 |

= 7/12 - 5/3 (since the absolute value of -7/12 is 7/12)

= 7/12 - 20/12

= -13/12

The simplified expression is -13/12.

_______________________

Simplify the following:

abs(5/6 - 17/12) - abs(5/3)

Put 5/6 - 17/12 over the common denominator 12. 5/6 - 17/12 = (2×5)/12 - 17/12:

abs(((2×5)/12 - 17/12)) - abs(5/3)

2×5 = 10:

abs(10/12 - 17/12) - abs(5/3)

10/12 - 17/12 = (10 - 17)/12:

abs(((10 - 17)/12)) - abs(5/3)

10 - 17 = -7:

abs((-7)/12) - abs(5/3)

Since 5/3 is a non-negative constant, abs(5/3) = 5/3:

abs(-7/12) - 5/3

Since -7/12 is a negative constant, abs(-7/12) = 7/12:

7/12 - 5/3

Put 7/12 - 5/3 over the common denominator 12. 7/12 - 5/3 = 7/12 + (4 (-5))/12:

7/12 - (5×4)/12

4 (-5) = -20:

7/12 + (-20)/12

7/12 - 20/12 = (7 - 20)/12:

(7 - 20)/12

7 - 20 = -13:

Answer: (-13)/12
