Answer 2

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
