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

Now, we substitute these values back into the expression:

-2 1/3 + (-0.45)*(-3 1/3)

Now, let's simplify each part of the expression:

Now, we can rewrite the expression as:

-7/3 + (-0.45) * (-10/3)

Simplifying the multiplication:

-7/3 + 4.5

Now, we need to convert 4.5 to a fraction:

4.5 = 9/2

Now, we can rewrite the expression as:

-7/3 + 9/2

To add these fractions, we need to find a common denominator, which is 6:

-14/6 + 27/6

Now, subtract the fractions:

= 13/6

Therefore, the final result is 13/6.
