Answer:

  A, D

Step-by-step explanation:

An appropriate ratio for cups and pints is ...

 (1 pint)/(2 cups)   or   (2 cups)/(1 pint)

The similar ratio involving the unknown will match the units of numerator and denominator to those of the unknown ratio:

  [tex]\dfrac{1\text{ pint}}{2\text{ cups}}=\dfrac{4\text{ pints}}{x\text{ cups}}\\\\ \text{or}\\\\ \dfrac{2\text{ cups}}{1\text{ pint}}=\dfrac{9\text{ cups}}{x\text{ pints}}[/tex]

These formulations of the problem match the first and last choices: A and D.

Additional comment

I would formulate the proportion so the unknown (x) is in the numerator. This makes the solution be one step.
