Answer 2

To solve this expression, we can start by simplifying each fraction.

-28 4/5 can be written as -28.8 13 5/7 can be written as 13.714 6 3/5 can be written as 6.6 2/3 can be left as is

Next, we can perform the arithmetic operations in the following order: multiplication and division, followed by addition and subtraction.

-28.8 : 13.714 = -2.1 (rounded to one decimal place) 6.6 : 2/3 = 9.9 -2.1 - 9.9 = -12 -3 3/11 can be written as -3.2727 (repeating decimal) (-9/11) can be left as is

Finally, we can subtract -9/11 from -3.2727:

-3.2727 - (-9/11) = -2.1818 (rounded to four decimal places)

Therefore, the expression simplifies to -2.1818.
