Question

The amount of protein a person needs each day is proportional to his or her weight. Rod weighs 165 pounds and needs 60 grams of protein each day. If Todd weighs 220 pounds, how much protein does he need each day?
Answer with supporting work:

Answer 1

The equation for this would be: $\frac{60}{165}= \frac{x}{220}$. first you want to multiply 60 by 220, then divide the product by 165.  60 times 220 is 13,200.  Now divide 13,200 by 165.  This will give you 80.  Todd has to eat 80 grams of protein each day to stay healthy.
