answer:Yes, it is possible. First, let’s say that Cereal X = 12 grams of vitamin C, and Cereal Y = 15 grams.* Calculate percent difference like this: (Y – X) / X * 100% (15 – 12) / 12 * 100% 3 / 12 * 100% 25% Now, let’s say that Cereal A = 12 grams and Cereal B = 27 grams.* (B – A) / A * 100% (27 – 12) / 12 * 100% 15 / 12 * 100% 125% *that is a lot of vitamin C
