Dried dog food comes in 5kg bags. A dog eats 400g each day. How long will the food last?

In column method

To find out how long the food will last, we have to determine the number of days it will take for the dog to consume the entire 5kg bag.

First, we need to convert 5kg to grams:
5kg = 5,000g

Next, we divide the total amount of food (5,000g) by the amount of food the dog eats each day (400g):
5,000g / 400g = 12.5

Therefore, the food will last for 12.5 days.

To find out how long the food will last, we can use the column method. Here's how:

1. First, convert the amount of dog food eaten per day from grams to kilograms. Since 1 kilogram is equal to 1000 grams, 400 grams is equal to 400/1000 = 0.4 kilograms.

2. Next, divide the total weight of the dog food (5 kilograms) by the amount of dog food eaten per day (0.4 kilograms):
5 kg / 0.4 kg/day = 12.5 days

Therefore, the dog food will last approximately 12.5 days.

To determine how long the food will last based on the given information using the column method, we can follow these steps:

1. Start by converting all the quantities to the same unit. In this case, we'll convert the weight of the dog food bag from kilograms (kg) to grams (g). Since 1 kg is equal to 1000 g, a 5 kg bag of dog food is equal to 5000 g.

2. Next, determine how many grams of food the dog eats each day. According to the given information, the dog eats 400g per day.

3. Now, we can divide the total weight of the dog food bag (5000 g) by the daily consumption (400 g) to find out how many days the food will last.

Using the column method:

5000 g ÷ 400 g
__________________________
400 g)5000.0 g(12.5 days
4000
__________
1000
800
__________
200

Therefore, the dog food will last for approximately 12.5 days.

Keep in mind that we obtained the decimal value 0.5 in the initial division. Since we cannot have half a day, we often round the decimal value either up or down depending on the specific situation or rounding conventions. In this case, since it is unlikely to divide the dog food into smaller portions, we can round the answer to the nearest whole number. By rounding down, we get a final result of approximately 12 days.
