You can put this solution on YOUR website!
ewatrrr had answered 21951 question the day before she answered your questions,
but the number is not part of her name.

The percent of calories from fat is the number of calories from fat per 100 total calories of the food.
It is a ratio: calories from fat divided by total calories.
So if a portion of food provides 169 calories,
but only 63 of those calories come from fat in the food,
then 69%2F169=0.408=40.8%2F100 is the fraction of calories that come from fat.
If you eat 100 calories worth of that food, you will be getting about 41 calories from the fat in the food.
That is 41 per hundred, or 41%.

What you should know is that a gram of fat provides 9 calories.
So, 7 grams of fat provide 7%2A%289Cal%29=63Cal ,
and 63 calories are
69%2F169=about0.41=41%2F100=%2241%25%22 of the 169 calories in the portion of tuna fish.
