To be able to determine what is 1/3 of the adult dose, we will be using the following formula:
[tex]\text{ }\frac{1}{3}\text{ of Adult dose = }\frac{1}{3}\text{ x 180 mg}[/tex][tex]\text{ }\frac{1}{3}\text{ of Adult dose = }\frac{180}{3}\text{ mg}[/tex][tex]\text{ }\frac{1}{3}\text{ of Adult dose = }60\text{ mg}[/tex]Therefore, 1/3 of the adult dose is 60 mg.
