To find the percentage of kilocalories from fat, multiply the grams of fat by 9 to get the kilocalories from fat (39g * 9kcal/g = 351 kcal). Then, divide the kilocalories from fat by the total kilocalories and multiply by 100 to get the percentage (351 kcal / 640 kcal * 100 = 54.84%, rounded to 55%).
