Questions: An apple contains 60 kcals. If 36 kcals are from carbohydrate, then how many grams of carbohydrate does this apple contain? 4 g 9 g 36 g 5 g

The answer is the second one (or B): 9 g.

Explanation:

1. To determine the grams of carbohydrate in the apple, we need to know the caloric value of carbohydrates. Carbohydrates provide 4 kcal per gram.
2. Given that 36 kcals are from carbohydrates, we can use the following formula to find the grams of carbohydrate: \[ \text{Grams of carbohydrate} = \frac{\text{Calories from carbohydrate}}{\text{Calories per gram of carbohydrate}} \]
3. Substituting the given values: \[ \text{Grams of carbohydrate} = \frac{36 \text{ kcal}}{4 \text{ kcal/g}} = 9 \text{ g} \]

Therefore, the apple contains 9 grams of carbohydrate.
