Calculation of Food Consumption for 8 Puppies in 4 Days

To calculate the amount of food 8 puppies will consume in 4 days, we can use the given information about the food consumption of 7 puppies in 5 days.

According to the information provided, 7 puppies consume 1 kg 400 g of food in 5 days.

To find out how much food 8 puppies will consume in 4 days, we can set up a proportion:

7 puppies consume 1 kg 400 g of food in 5 days

8 puppies will consume x kg of food in 4 days

Using the proportion, we can solve for x:

(7 puppies / 8 puppies) = (1 kg 400 g / x kg)

Cross-multiplying, we get:

7 * x = 8 * (1 kg 400 g)

Simplifying the right side of the equation:

7 * x = 8 * 1.4 kg

7 * x = 11.2 kg

Dividing both sides by 7:

x = 11.2 kg / 7

x ≈ 1.6 kg

Therefore, 8 puppies will consume approximately 1.6 kg of food in 4 days.

Answer:

8 puppies will consume approximately 1.6 kg of food in 4 days.
