#### Answer

Required proportion : $\frac{8.2 grams}{50 pounds} = \frac{x grams}{145 pounds}$
Solution : $x \approx 24$,
i.e. 24 grams of medication can be given for the person weighing 145 pounds.

#### Work Step by Step

A medication is given at the rate of 8.2 grams for every 50 pounds of body weight. How much should be given to a 145-pound person?
As per the details given: $\frac{8.2 grams}{50 pounds} = \frac{x grams}{145 pounds}$ (Assumed x as a required gms of medication)
i.e. $8.2 \times145 = 50 \times x$ (As bot sides have same numerator and denominator)
Now, divide both sides by 50,
$1189 \div 50 = 50 x \div 50$
$ x = 23.78 \approx 24 $
