-13/46-3/4-61/120+11/30-7/12=

Compute with a common denominator (2760):

-13/46 = -780/2760 -3/4 = -2070/2760 -61/120 = -1403/2760 +11/30 = +1012/2760 -7/12 = -1610/2760

Sum: (-780 - 2070 - 1403 + 1012 - 1610) / 2760 = -4851/2760

Reduce by gcd(4851, 2760) = 3: -4851/2760 = -1617/920

Final answer: -1617/920.
