First rewrite the fractions to have a common denominator.
2/3 = 8/12 , 1/2 = 6/12 and 3/4 = 9/12
Now you have:
-7 8/12 + (-5 6/12) + 8 9/12
-7 8/12 + (-5 6/12) becomes -7 8/12 - 5 6/12 = -13 2/12
Now you have
-13 2/12 + 8 9/12 = -4 5/12
Answer: -4 5/12
Step-by-step explanation:
-7(⅔) + -5(½) + 8(¾)
-23/3 + (-11/2) + 35/4
-92 - 66 + 105/12
-154 + 105/12
-49/12
