Question

Стадо молодняка состоит из бычков и телочек. Телочек в стаде 55% от его общей численности, а их общий вес составляет 45% общего веса стада. Во сколько раз средний вес бычка больше среднего веса телочки?

Answer 1

45/55=9/11-средний вес телочки

55/45=11/9-средний вес бычка

11/9:9/11=11/9*11/9=121/81=1 40/81- во столько раз средний вес бычка больше среднего

веса телочки

Answer 2

Calculation of Average Weight

To find the ratio of the average weight of a bull (bychka) to the average weight of a heifer (telochka), we need to use the given information about the percentage of heifers in the herd and their total weight compared to the total weight of the herd.

According to the information provided, the heifers make up 55% of the total number of animals in the herd, and their total weight is 45% of the total weight of the herd.

Let's assume that the total number of animals in the herd is 100 for simplicity.

- The number of heifers in the herd is 55% of 100, which is 55. - The number of bulls in the herd is 45% of 100, which is 45.

Now, let's calculate the average weight of the heifers and the average weight of the bulls.

Since we don't have specific weight values for each individual animal, we'll use a hypothetical weight of 1 unit for each animal.

- The total weight of the heifers is 55 units (55 heifers * 1 unit per heifer). - The total weight of the bulls is 45 units (45 bulls * 1 unit per bull).

Calculation of Average Weight Ratio

To find the ratio of the average weight of a bull to the average weight of a heifer, we divide the total weight of the bulls by the total weight of the heifers.

- The average weight of a heifer is the total weight of the heifers divided by the number of heifers, which is 55 units / 55 heifers = 1 unit. - The average weight of a bull is the total weight of the bulls divided by the number of bulls, which is 45 units / 45 bulls = 1 unit.

Therefore, the average weight of a bull is equal to the average weight of a heifer.

The average weight of a bull is not greater than the average weight of a heifer.

Please note that the calculations above are based on the assumption of a hypothetical weight of 1 unit for each animal. The actual weights may vary, but the ratio of the average weights remains the same.
