Question: how do you calculate percentage of fat grams?
Answer: Multiply the grams of saturated fat by 9 = (xx) the number of saturated fat calories in the food item. b. Divide (xx) the number of saturated fat calories in the food item by the total number of calories in the food item = % of saturated fat. 1) Fat – 3 x 9 = 27 fat calories; 27/90 = 30% total fat.
