First, let's simplify each part of the equation:

(26.7 - 13 1/5) = 26.7 - 13.2 = 13.5

13 1/5 = 13.2

13.5 / 1.8 = 7.5

1.88 + 2 3/25 = 1.88 + 2.12 = 4

22 * 3/55 = 1.2

Now, let's substitute these values back into the original equation:

(7.5) + 0.125 (4) + 1.2

Now, let's calculate the multiplication first:

0.125 * 4 = 0.5

Finally, let's add the remaining values:

7.5 + 0.5 + 1.2 = 9.2

Therefore, the final answer is 9.2.
