math calculations with pediatric rule

A seven-year-old child is to receive a dose of acetaminophen that has an adult dose of 600 mg. What is the pediatric dose?
------------------------------------------------------------
Using Young's rule:
(age of child in years / (age + 12 years)) * adult dose

(7 / (7 + 12)) * 600
(7 / 19) * 600
221 mg is the pediatric dose

A 90-pound (lb) child is to receive a dose of acetaminophen that has an adult dose of 700 mg. What is the pediatric dose?
------------------------------------------------------------
Using Clark's rule:
(weight of child in lb / 150 lb) * adult dose

(90 / 150) * 700
0.6 * 700
420 mg is the pediatric dose
