Answer:

Hence, option C is true.
Step-by-step explanation:
Given the expression

Solving for 'm'

Flip the equation

Expanding by applying the distributive law: 

Add (-1)/2 × kn to both sides

simplify

Divide both sides by k/2


Therefore,

Hence, option C is true.

Answer:
   Find the LCD of the first two, then the LCD of that and the third one.
Step-by-step explanation:
You can do it by finding the LCD of two of the denominators, then the LCD of that and the third denominator.
Or, you can factor each of the denominators and find their LCM by multiplying the unique factors to their highest powers.
___
<u>Example:</u>
   1/21 + 1/35 + 1/45
The LCD of 1/21 and 1/35 is (21·35)/5 = 105. The LCD of 1/105 and 1/45 is ...
   (105·45)/15 = 315
__
Using factoring ...
- 21 = 3·7
- 35 = 5·7
- 45 = 3²·5
LCD = 3²·5·7 = 315
