Final answer:
To find the percentage of energy supplied by carbohydrates, divide the energy from carbohydrates (100 kcal) by the total energy (140 kcal) and multiply by 100, which results in 71.43%.
Step-by-step explanation:
To calculate the percentage of energy supplied by carbohydrates, we can use the information given about the total energy and the energy from carbohydrates. The total energy is given as 140 kilocalories, and the energy from carbohydrates is given as 100 kilocalories.
We can calculate the percentage by dividing the energy from carbohydrates by the total energy and then multiplying b
Percentage of energy from carbohydrates = (Energy from carbohydrates / Total energy) × 100
Percentage of energy from carbohydrates = (100 kcal / 140 kcal) × 100
Percentage of energy from carbohydrates = 0.714285714 × 100
Percentage of energy from carbohydrates = 71.43%
Thus, 71.43% of the energy is supplied by carbohydrates.
