Kristin adds 1 tablespoon of chopped walnuts to cup cooked
Kristin adds 1 tablespoon of chopped walnuts to ½ cup cooked quinoa. This mixture provides about 160 kcal, 7 g fat, 19 g carbohydrate, and 5 g protein. Calculate the approximate percentages of total kcalories in a serving of the mixture that are contributed by fat (yellow), carbohydrate (blue), and protein (orange) and fill in the pie chart according to your calculations. Rounding the figures may be necessary to obtain 100%. To enter the percentages, click on the pencil icon in the upper left corner of each label, type in the number (do not include the percentage sign), click on the save icon in the upper left corner and drag the label to the appropriate place on the pie chart.
Solution
fat gives 9 calories per gram. so, 7gm will give 63 calorie.
protein and carbohydrates give 4 calories per gram. so that will be (19+5)*4=96 calorie
total calorie by fat, carbohydrate,protein= 63+96=159 calorie. approximate with 160 calorie.
total calorie= 160 kilocalorie
percent contribution=160/(160*1000)*100=0.1%
