Final answer:

To calculate the percentage of carbohydrates in different food items, divide the amount of carbohydrates by the total weight of the product and multiply by 100. The couscous contains 29% carbohydrates, the maize flour 78%, and the wheat flour 64%.

Explanation:

The question requires calculating the percentage of carbohydrates in different food items based on their given weights and carbohydrate contents.

  1. For the 400g pack of couscous with 116g of carbohydrates, the percentage of carbohydrates is calculated as: (116g / 400g) * 100 = 29%.
  2. For the 250g bag of maize flour with 195g of carbohydrates, the percentage of carbohydrates is: (195g / 250g) * 100 = 78%.
  3. For the 1kg (1000g) bag of wheat flour with 640g of carbohydrates, the percentage of carbohydrates is: (640g / 1000g) * 100 = 64%.

Thus, each food item has a different carbohydrate content, with maize flour having the highest percentage.
