The amount of protein a person needs each day is proportional to his or her wait. Rod weighs 165 pounds and needs 60 grams or protein each day. If Todd ways 220 pounds, how much protein does he need each day

It is a proportion problem. it is 60/165 = x / 220 cross multiply. 165x=13200.

divide both sides by 165. X=80

If you would like to know how much proteins does Todd need each day, you can calculate this using the following steps:

165 pounds ... 60 grams

220 pounds ... x grams = ?

165 * x = 60 * 220 / 165

x = 60 * 220 / 165

x = 80 grams

Result: Todd needs 80 grams of proteins each day.
