The percentage of the total energy contributed by fat = 51.59% of fat
<h3>Calculation of total energy in fat</h3>
The quantity of fat in the hamburger = 36grams
But 1 gram of fat = 9 kcal( standard energy value per gram of fat).
That is , 9kcal = 1 gram
X kcal = 36 grams
cross multiply,
X kcal = 9 × 36
= 324kcal
To calculate the percentage of 324kcal of fat in 628 kcal,
% = 51.59% of fat
The percentage of the total energy contributed by fat = 51.59%
