To solve this problem, we need to simplify each fraction first and then perform the subtraction:
11/15 = 0.7333...
9/20 = 0.45
1/30 = 0.0333...
Now, let's subtract these fractions:
3 + 0.45 + 1.0333 - (7 + 0.7333)
3.45 + 1.0333 - 7.7333
4.4833 - 7.7333 = -3.25
Therefore, the result of the expression is -3.25.
