First, we simplify the terms within each set of parentheses:

3 + 1/5 = 15/5 + 1/5 = 16/5

12 + 1/3 = 36/3 + 1/3 = 37/3

1 + 1 = 2

1/1 + 2/3 = 1 + 2/3 = 3/3 + 2/3 = 5/3

Now we substitute these values back into the original expression:

(16/5 + 37/3) + 2 + (1/3 + 3/4) - (1 + 5/3)

Now we add and subtract:

(16/5 + 37/3) = (48/15 + 185/15) = 233/15

(1/3 + 3/4) = (4/12 + 9/12) = 13/12

(1 + 5/3) = (3/3 + 5/3) = 8/3

Now substitute back into the original expression:

233/15 + 2 + 13/12 - 8/3

Now we find a common denominator for the fractions:

15 * 12 = 180

(233 12 + 2 180 + 13 15 - 8 60) / 180

(2796 + 360 + 195 - 480) / 180

(3371 - 480) / 180

2891 / 180

Therefore, the final answer is 2891/180
