Explanation

Time to Plug In! If you make m = 2 and n = 3, then Quantity A becomes \(\frac{2}{2*3}=\frac{1}{3}\), and Quantity B becomes \(\frac{3}{2*3}=\frac{1}{2}\). Quantity B is bigger; eliminate choices (A) and (C). However, if you make and n = 2, then the situation is reversed: Quantity A will be \(\frac{1}{2}\), and Quantity B will be \(\frac{1}{3}\). Eliminate choice (B); the answer must be choice D.
