-7 2/3 + (-5 1/2) + 8 3/4

First, express the mixed numbers as simple fractions:

-7 2 /3 = - (7x3+2) /3 = -23/3

- 5 1/2 = - (5x2+1) /2 = -11 /2

8 3/4 = (8x4+3) / 4 = 35/4

Now we have

-23/3 + (- 11/2 ) + 35/4

-23/3 - 11/2 + 35/4

Find the LCM = 12

-92/12 - 66/12+ 105/12

Add and subtract

(-92-66+105) /12

-53/12

As a mixed number

-4 5/12
