To find out how many eggs 1 chicken lays in 1 day, we can start by understanding the given information: 1.5 chickens lay 1.5 eggs in 1.5 days. This can be simplified to find the rate at which one chicken lays eggs. Here's how we can approach it:

Find the egg-laying rate per chicken per day: We need to normalize the given data to understand the rate for one chicken in one day.
Calculate for 1 chicken in 1 day: Once we have the rate per chicken per day, we can easily find out how many eggs 1 chicken lays in 1 day.
Let's do the math based on the information provided.

Based on the calculation, 1 chicken lays approximately 0.67 eggs in 1 day.

# Given data
chickens = 1.5
eggs = 1.5
days = 1.5

# Calculate the rate of eggs laid per chicken per day
eggs_per_chicken_per_day = eggs / (chickens * days)

# Output the result
eggs_per_chicken_per_day
