A physician prescribes for a patient 30 mg of lisinopril once a day. Each tablet of lisinoprilis 10 mg. What is the correct proportion to determine how many tablets of lisinopril the patient needs to take?
OA 30 mg/1 tab = 10 mg/x tab
OB. 1 tab/30 mg = 10 mg/x tab
OC. 10 mg/1 tab = 30 mg/x tab
OD. 10 mg/1 tab = x tab/30 mg
