×=1/5/1:(9/2-18/1)-8/5

First, let's simplify the expression inside the parentheses:

9/2 - 18/1 = 9/2 - 18 = 9/2 - 36/2 = -27/2

Now, let's simplify the expression further:

1:(-27/2) = 1 * (-2/27) = -2/27

Now, let's subtract 8/5:

-2/27 - 8/5 = -2/27 - 216/135 = -2/27 - 216/135 = -2/27 - 32/27 = -34/27

Therefore, the final answer is -34/27.
