Question

В инкубатор заложили 1200 яиц. из 23/24 всех яиц вылупились цыплята. при этом оказалось, что петушки состовляют 2/5 всех вылупившихся цыплят. Сколько петушков и сколько курочек вылупилось из яиц?

Answer 1

Было 1200 яиц
23\24 - это 1150 яиц(1200 делим на 24 и умножаем на 23)
теперь 1150 делим на 5 и умножаем на 2 = 460 петушков
1150- 460=690 курочек

Answer 2

Calculation of the Number of Roosters and Hens Hatched

To determine the number of roosters and hens hatched from the incubator, we can use the information provided in the question.

According to the question, 23/24 of all the eggs hatched into chicks, and 2/5 of all the hatched chicks are roosters.

Let's calculate the number of roosters and hens:

1. Calculate the total number of chicks hatched: - 23/24 of 1200 eggs hatched into chicks. - Number of chicks hatched = (23/24) * 1200.

2. Calculate the number of roosters: - 2/5 of the hatched chicks are roosters. - Number of roosters = (2/5) * (23/24) * 1200.

3. Calculate the number of hens: - The remaining chicks that are not roosters are hens. - Number of hens = (1 - 2/5) * (23/24) * 1200.

Let's calculate the values:

1. Number of chicks hatched: - Number of chicks hatched = (23/24) * 1200 = 1150.

2. Number of roosters: - Number of roosters = (2/5) * (23/24) * 1200 = 230.

3. Number of hens: - Number of hens = (1 - 2/5) * (23/24) * 1200 = 920.

Therefore, from the 1200 eggs in the incubator, 1150 chicks hatched, including 230 roosters and 920 hens.
