Answer 2

Calculating Paint Usage

To solve this problem, we'll need to calculate the total amount of paint used for painting the windows, doors, and floor. We are given the following information: - 3 1/2 kg of paint for the windows - 5 3/10 kg less paint for the doors than for the floor - 2 4/5 kg of paint used for the doors

Let's break this down step by step.

Paint Usage for Windows

The amount of paint used for the windows is 3 1/2 kg.

Paint Usage for Doors

We are told that the amount of paint used for the doors is 5 3/10 kg less than the amount used for the floor, and the amount used for the doors is 2 4/5 kg.

To find the amount of paint used for the floor, we can add the amount used for the doors to the amount less used for the doors than for the floor: - 5 3/10 kg less than the floor + 2 4/5 kg for the doors = 5 3/10 + 2 4/5 kg

Let's calculate the total amount of paint used for the doors.

Total Paint Usage

Now, we can calculate the total amount of paint used by adding the paint used for the windows to the paint used for the doors and the floor.

I'll calculate the total paint usage.
