Question

Задача В пшеничном хлебе содержится около 7 % белков и 45% углеводов . Сколько граммов остальных веществ содержится в 400 г пшеничного хлеба ????

Answer 1

400г=100%
45%+7%=52% - белки и углеводы
100%-52%=48%
400 грамм/100%=Х грамм/48%
Х=400*48/100=192 грамма

Answer 2

Calculation of Other Substances in 400g of Wheat Bread

To calculate the amount of other substances in 400g of wheat bread, we need to subtract the percentage of protein and carbohydrates from 100%.

Given that wheat bread contains approximately 7% protein and 45% carbohydrates, we can calculate the percentage of other substances as follows:

- Percentage of protein: 7% - Percentage of carbohydrates: 45%

To find the percentage of other substances, we subtract the sum of protein and carbohydrates from 100%:

Percentage of other substances = 100% - (percentage of protein + percentage of carbohydrates)

Percentage of other substances = 100% - (7% + 45%)

Percentage of other substances = 100% - 52%

Percentage of other substances = 48%

Therefore, the other substances make up approximately 48% of the total weight of wheat bread.

To find the weight of the other substances in 400g of wheat bread, we can calculate:

Weight of other substances = (Percentage of other substances / 100) * Total weight of wheat bread

Weight of other substances = (48% / 100) * 400g

Weight of other substances = 0.48 * 400g

Weight of other substances = 192g

Therefore, there are approximately 192 grams of other substances in 400 grams of wheat bread.

Please note that the values provided are approximate and may vary depending on the specific composition of the wheat bread.
