    0.058 % kcalories comes from carbohydrate.

    Explanation:

    1 g of carbohydrtes gives 4 calories, 1 g of protein gives 4 kcalories, 1 gm of fat gives 9 calories and 1 g of alcohol gives 7 calories of energy.

    Thus in a meal that contains 110 g carbohydrates gives 110 x 4 = 440 calories, 25 g protein gives 25 x 4 = 100 calories, 20 g fat gives 20 x 9 = 180 calories and 5 g alcohol gives 5 x 7 = 35 calories.

    Total calories in a meal 440+100+180+35 = 755.

    Therefore % of carbogydrate will be 440x 100 divided by 755 = 58.27 %

    In kcalories % would be 58.27/1000 = 0.5827 %
