Calculating the Number of Cows

To calculate the number of cows that can produce twenty-one buckets of milk in a week, we can use the given information that two cows produce three liters of milk in two days.

Given: - Two cows produce three liters of milk in two days.

To find the number of cows needed to produce twenty-one buckets of milk in a week, we can use the following steps:

1. Calculate the amount of milk produced by two cows in a week. 2. Use this information to find the number of cows needed to produce twenty-one buckets of milk in a week.

Calculation

1. Milk Production by Two Cows in a Week: - Two cows produce three liters of milk in two days. - There are seven days in a week. - Using the given information, we can calculate the amount of milk produced by two cows in a week.

Calculation: - Milk produced by two cows in two days = 3 liters - Milk produced by two cows in a week = (3 liters) * (7 days / 2 days) = 10.5 liters

2. Number of Cows Needed to Produce Twenty-One Buckets of Milk in a Week: - Now, we can use the amount of milk produced by two cows in a week to find the number of cows needed to produce twenty-one buckets of milk in a week.

Calculation: - Number of cows needed = (21 buckets) / (10.5 liters) = 2 cows

Therefore, two cows can produce twenty-one buckets of milk in a week.

This calculation is based on the given information and the conversion of buckets to liters for consistency.
