Question

In column method

Answer 1

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.
