Aisha with anorexia nervosa consumes 12 g of fat per day and a total of 1,100 kcal. What percentage of daily intake is from fat?

Explanation:
The key idea is to convert fat grams into kilocalories and then see what fraction of total calories they represent. Fat provides about 9 kcal per gram. So fat calories = 12 g × 9 kcal/g = 108 kcal. With a total intake of 1,100 kcal, the fat contribution is 108/1,100 = 0.098, or about 9.8%, which rounds to 10%. The other percentages would require fat to contribute 88 kcal (8%), 132 kcal (12%), or 165 kcal (15%), which doesn’t match the actual 108 kcal. So the correct percentage is 10%.
