Final answer:
To find the percentage of kcalories that are coming from fat, divide the number of kcalories from fat by the total number of kcalories and multiply by 100. In this case, the percentage is approximately 55.94%.
Step-by-step explanation:
To find the percentage of kcalories that are coming from fat, we need to divide the number of kcalories from fat by the total number of kcalories and multiply by 100.
In this case, Emma consumed 439 kcalories, with 27 grams of fat. Since each gram of fat provides 9 kcalories, the total kcalories from fat can be calculated as 27 g * 9.1 kcal/g = 245.7 kcal.
Therefore, the percentage of kcalories coming from fat is (245.7 kcal / 439 kcal) * 100 = 55.94%.
