Step-by-step explanation:

Cephalexin is an antibiotic that is prescribed in 500-mg tablets and a doctor prescribes 2 grams of cephalexin each day for a patient.

To get the number of 500-mg tablets that would have to be taken in order to achieve the daily dosage goes this:

1000 milligrams= 1 gram

Therefore, 2 grams= 2 × 1000= 2000 milligrams.

Since the drugs are sold in 500mg and the patient is expected to take 2grams which is 2000mg. We divide: 2000 ÷ 500 = 4

The patient is expected to take 4 500-mg tablets to achieve this daily dosage.
