Answer 2

Problem Analysis

To solve this problem, we need to determine how much butter is left after selling two-fifths of the 56 boxes of butter, with each box containing 20 kilograms.

Solution

To find out how much butter is left, we need to calculate two-fifths of the total amount of butter and subtract it from the initial amount.

1. Calculate the total amount of butter: - Number of boxes: 56 - Kilograms per box: 20 - Total amount of butter: 56 boxes * 20 kilograms/box = 1120 kilograms .

2. Calculate two-fifths of the total amount of butter: - Two-fifths of 1120 kilograms = (2/5) * 1120 kilograms = 448 kilograms.

3. Subtract the amount of butter sold from the total amount to find out how much is left: - Amount of butter left = Total amount of butter - Amount of butter sold = 1120 kilograms - 448 kilograms = 672 kilograms.

Answer

After selling two-fifths of the butter, there are 672 kilograms of butter left.
