To simplify this expression, we need to perform the division first and then the subtraction.
First, let's divide 2 by 8/9:
2 ÷ (8/9)= 2 * (9/8)= 18/8= 9/4
Now, let's subtract 9/4 from 31/35:
31/35 - 9/4= (314 - 935) / (35*4)= (124 - 315) / 140= -191 / 140
Therefore, the simplified expression is -191/140.

31/35 - 9/4
= (314 - 935) / (35*4)
= (124 - 315) / 140
= -191 / 140
Therefore, the simplified expression is -191/140.
