One container has 28 kilograms of flour and another has 4 kilograms.How many kilograms must be taken from one container, so each has an equal amount offlour?

To solve this problem, you first need to find the total amount of flour. You do this by adding the amount of flour in both containers.

28 kg (from the first container) + 4 kg (from the second container) = 32 kg

Next, you need to divide the total amount of flour by 2 because you want to distribute it equally between the two containers.

32 kg ÷ 2 = 16 kg

This means that each container should have 16 kg of flour.

The first container currently has 28 kg, so you need to subtract the desired amount (16 kg) from the current amount (28 kg) to find out how much flour you need to remove.

28 kg - 16 kg = 12 kg

So, you need to remove 12 kilograms of flour from the first container to make sure both containers have an equal amount of flour.
