Question

D = a/(a + 12). If D equals 2 dosage in milligrams, a equals weight of the child, and m equals adult dosage in milligrams, what is 1/3 of the adult dosage if the adult dosage of the medicine is 180 mg?

a. 45 mg.
b. 60 mg.
c. 90 mg.
d. 120 mg

Answer 1

To find 1/3 of the adult dosage, multiply the adult dosage by 1/3. Therefore, 1/3 of the adult dosage is 60 mg.

Step-by-step explanation:

To find 1/3 of the adult dosage, we need to multiply the adult dosage by 1/3. The adult dosage is given as 180 mg, so we can find 1/3 of that by multiplying 180 by 1/3.

180 * 1/3 = 60 mg

Therefore, 1/3 of the adult dosage is 60 mg. Therefore, the correct answer is b. 60 mg.
