Answer:
2.4 teaspoons
Explanation:
The label on the prescription says there are 2 mg for every 4 ml of the cough medicine. We need to determine the volume of 6 mg of this cough medicine using the following relation;
2 mg = 4 ml
6 mg = ?
( 6 * 4) / 2 = 24/2 = 12 ml
This implies that the volume of the 6 mg of the cough medicine is 12 ml. Now, the volume of a standard dosing teaspoon is 5 ml. We need to determine the number of teaspoons that will hold the 12 ml. We use the following relation;
1 teaspoon = 5 ml
? = 12 ml
(1*12) / 5 = 12/5 = 2.4 teaspoons
