If a food label identifies the total number of kilocalories in a bowl of cereal as 140 and the carbohydrate kilocalories as 100, what is the approximate percentage of energy supplied by carbohydrates?40506070
70
To calculate the percentage of energy supplied by carbohydrates, we need to divide the carbohydrate kilocalories by the total kilocalories and then multiply this number by 100 to get the percentage:
Carbohydrate kilocalories / Total kilocalories = Percentage of energy supplied by carbohydrates
In this case, the carbohydrate kilocalories are 100 and the total kilocalories are 140.
100 / 140 = 0.714
To convert this decimal to a percentage, we multiply by 100:
0.714 x 100 = 71.4%
Therefore, approximately 71.4% of the energy supplied by the bowl of cereal comes from carbohydrates.
