Answer 2

Calculating the Number of Painted Floors

To determine the number of floors already painted, we can use the information provided about the remaining number of apartments to be painted and the number of apartments on each floor.

Given: - Total number of apartments: 54 - After painting several floors with 6 apartments on each floor, 18 apartments are left to be painted.

Let's calculate the number of floors already painted.

Solution:

1. First, we find the total number of apartments painted. - Total number of apartments = 54 - Remaining apartments to be painted = 18 - Total apartments painted = Total - Remaining - Total apartments painted = 54 - 18 - Total apartments painted = 36 2. Next, we calculate the number of floors already painted. - Number of apartments on each floor = 6 - Number of floors painted = Total apartments painted / Apartments on each floor - Number of floors painted = 36 / 6 - Number of floors painted = 6

Conclusion:

The brigade of painters has already painted 6 floors.
