In a farm, on average every 6 cows produce 108 litres of milk per week. In five weeks the cows produced 2160 litres of milk. How many cows are in the farm?
2160L * 6cows/108L = 120 cows
including the units in your calculations makes it easy to keep track of what to multiply or divide, so that the unwanted units cancel out.
This is just a conversion problem (convert liters to cows), where 6cows/180L is the conversion factor.
In a farm, on average every 6 cows produce 108 litres of milk per week. In five weeks the cows produced 2160 litres of milk. How many cows are in the farm?
12960/108
= 120
To find the number of cows on the farm, we need to divide the total amount of milk produced by the average milk produced by each cow per week.
First, let's calculate the average milk production per cow per week:
108 liters/week ÷ 6 cows = 18 liters/cow/week
Now, we can find the total number of cows on the farm by dividing the total milk production over the five weeks by the average milk production per cow per week:
2160 liters ÷ (18 liters/cow/week * 5 weeks) = 240 cows
Therefore, there are 240 cows on the farm.
