Answer:
19%
Explanation:
It is known that a gram of fat contains 9 calories
Now; in 30 grams of fat; the number of calories will be: 30 × 9 =270 calories
The _____ percentage of the total energy from 1400 kcalories can now be determined as:
= [tex]\frac{270}{1400}[/tex]
= 0.19
= 19%
∴ Approximately 19% of the total energy is provided by fat.
