Question

A certain medicine is given in an amount proportional to a patient's body weight. Suppose a patient weighing 100  pounds requires  125 milligrams of medicine. What is the amount of medicine required by a patient weighing 216 pounds?

anonymous · Answer

The patient is 216/100 times heavier than the 100 pounds patient so need 216/100 times the amount. Hopefully that's enough of a clue.

anonymous · Answer

Create a proportion: 100lb/125mg = 216lb/ x mg.
Cross multiply; 100x=125*216

x= 270 mg

125/100 x 216 = 270... i would say 270 milligraams of medicine:)
