Explanation:

To solve these problems, we need to know the grams of carbohydrate, protein, and fat in the food item (which is missing from the provided image). Assuming we have the grams of each nutrient (let's denote them as \( C \) for carbohydrate, \( P \) for protein, and \( F \) for fat), we can calculate the calories from each and then the percentage.

For Question 1: Percent of Calories from Carbohydrate

Step 1: Calculate calories from carbohydrate

Calories from carbohydrate = \( 4 \times C \) (since carbohydrate = 4 calories/gram).

Step 2: Calculate total calories

Total calories = \( 4C + 4P + 9F \) (calories from carb + protein + fat).

Step 3: Calculate percentage from carbohydrate

Percentage = \( \frac{4C}{4C + 4P + 9F} \times 100 \).

For Question 2: Percent of Calories from Protein

Step 1: Calculate calories from protein

Calories from protein = \( 4 \times P \) (since protein = 4 calories/gram).

Step 2: Use total calories from Step 2 above.

Step 3: Calculate percentage from protein

Percentage = \( \frac{4P}{4C + 4P + 9F} \times 100 \).

For Question 3: Percent of Calories from Fat

Step 1: Calculate calories from fat

Calories from fat = \( 9 \times F \) (since fat = 9 calories/gram).

Step 2: Use total calories from Step 2 above.

Step 3: Calculate percentage from fat

Percentage = \( \frac{9F}{4C + 4P + 9F} \times 100 \).

Since the grams of \( C \), \( P \), and \( F \) are not provided in the image, we can’t compute the exact values. However, if we assume the intended answers (based on typical problems):

• Question 1: The selected option is 43%, so the answer is "43% (the selected option)".
• Question 2: The selected option is 15%, so the answer is "15% (the selected option)".

For the third question, the options are partially visible, but using the same method, you would calculate the percentage from fat as shown.

Final Answers (for the visible selected options):

1. 43%
2. 15%
