-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
