Answer 2

Answer: 333.75mg

Explanation:

Given data:

Dose for 180lb man = 445mg

Dose for 135lb man = ?

let the unknown be x

= 445 / 180 * x / 135

cross multiply both sides

180x = 445 * 135

180x = 60075

Divide both sides by 180

180x / 180 = 60075 / 180

x = 333.75mg

Therefore; a man who weighs 135lbs would require 333.75mg
