3.4 grams of fat, then your equation might look like
3.4 X 9 =
30.6.
This food would have
30.6 calories from fat. , After you have calculated the number of calories in the food that are from fat, you can convert this number to a percentage.
To get the percentage of calories from fat in a food, just divide the number of calories from fat in one serving by the total number of calories in one serving.For example, if the food has 260 calories in a serving and
30.6 calories from fat, then your equation might look like
30.6 / 260 =
0.1176 To turn this result into a percentage, just move the decimal two spots to the right or multiply your result by
100.
For example,
0.1176 X 100 =
11.76% or about 12%.
This means that the food has a fat percentage of about 12%. -
