Answer:

A

Explanation:

Essentially, to use the method of division the question is mentioning you need to divide 21 by 3/4. Use fraction rules to divide meaning (21*4/3). This gets you m + 12 = 84/3. If you simplify the right side you get 28. Thus, the final answer is the first option choice.

Hope this helped :)
