Question

suppose a patient weighing 104 pounds requires 156 mL of medicine what is it weight of a patient requires 207 milligrams of Medicine

Answer 1

This is a proportion problem, setting up the proportion is the hard part, but once you get that, the calculations are easy.

So, lets set one up

(Let x = the weight of the patient)

`(104lbs)/(156mg) = (x)/(207mg)`

Now, Just cross multiply and solve.

104*207 = 156 *x

21528 = 156x

138 = x

The patient requiring 207 miligrams of medicine weighs 138 lbs.
