Answer:
Step-by-step explanation:
Givens:
m: 2/3 m and 5/6 m
rational numbers: -1 1/6 and - 1 1/3
Combine the givens
2/3 m + 5/6 m Change 2/3 m to something over 6
2/3m = 2*2 m / 3*2
2/3 m = 4 m /6
4m/6 + 5m / 6 = 9 m/6 = 1 1/2 m
Result: B and D are both incorrect
Now work on the rationals. Change the -1 1/3 into -1 something / 6
Change 1/3 into something over 6
-1 1/6 - 1 1/3 change - 1 1/3 = -1 2*1 /3*2
-1 1/6 - 1 2/6
-1 1/6 - 1 2/6 = 2 (1 + 2)/6
-1 1/2
Answer: C
