Answer 2

Calculation of the Number of Roosters and Hens Hatched

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

According to the question, 23/24 of all the eggs hatched into chicks. Let's calculate the total number of chicks hatched:

1) Total number of chicks hatched = 1200 * 23/24 = (1200 * 23) / 24 = (50 * 23) / 1 = 1150.

Next, we are given that 2/5 of all the hatched chicks are roosters. Let's calculate the number of roosters:

2) Number of roosters = 1150 * 2/5 = (1150 * 2) / 5 = (230 * 2) / 1 = 460.

To find the number of hens, we subtract the number of roosters from the total number of chicks hatched:

3) Number of hens = 1150 - 460 = 690.

Therefore, from the 1200 eggs, 460 roosters and 690 hens hatched.

Answer: - Number of roosters hatched: 460 - Number of hens hatched: 690
