First, we need to convert all mixed numbers to improper fractions:

11 25/1 = 11+ 25/1 = 11+ 25 = 36
3 5/12 = 3+ 5/12 = 3+ 5/12 = 3(12) + 5 = 36 + 5 = 41

4 3/1 = 4+ 3/1 = 4+ 3 = 7
7 19/30 = 7 + 19/30 = 7 + 19/30 = 7(30) + 19 = 210 + 19 = 229

7 7/12 = 7 + 7/12 = 7 + 7/12 = 7(12) + 7 = 84 + 7 = 91
5 5/6 = 5 + 5/6 = 5 + 5/6 = 5(6) + 5 = 30 + 5 = 35

Now we can substitute the values into the expression:

(36 - 41) + (7 7/12 - 5 5/6)
= -5 + (91 - 35)
= -5 + 56
= 51

Therefore, (11 25/3 - 35 5/12 + 4 3/1 - 7 19/30) : (7 7/12 - 5 5/6) equals 51.
