Let's simplify this expression step by step:
First, (1/9) * 2 = 2/9.
Now, we have 18 (2/9) - 20 (1/9).
Next, 18 * (2/9) can be simplified to 36/9, which equals 4.
So, the expression now becomes 4 - 20 * (1/9).
Finally, 20 * (1/9) simplifies to 20/9.
Therefore, the final simplified expression is:
4 - 20/9
