The patient is to take 1,500 mg PO daily of Medication Q. The pharmacy dispenses a bottle of Medication Q labeled "750 mg tablets." The nurse sets up the following proportion:

750 mg: 1 tablet :: 1,500 mg: x tablet

Which of the following represents the correct multiplication of the means and extremes?

750 x 1,500 = 1 xX

1 x 1,500 = 750 × X

1 x x = 750 × 1,500
