maximum # of grams of fat (F) that should be in a diet varies directly as a person's weight (W). A person weighing 147lbs should have no more than 98g of fat per day. What is the maximum daily fat intake for a person weighing 78lbs?
147 78 ---- = ----- 98 X
is the answer 52g
this is ratio and proportion. a person weighing 147 should get 98g of fat per day, so a person weighing 78 pounds should get a proportionate amount of fat with repesct t their weight. so 98/147 should be equal to F/78 F = 78*98/147
