Answer:
2.5 tablets
Explanation:
One milligram is a thousandth of a gram, so 30mg is 0.03g.
This means each tablet contains 0.03g of the antibiotic.
The patient needs 0.075g of the antibiotic.
By dividing the number of grams the patient needs by the grams per tablet, we find that the patient will need 2.5 tablets of antibiotic.
