Answer 1

24:6=4 маляр за 1 час;
18:6=3 ученик за 1 час;
4+3=7 маляр и ученик вместе за 1 час;
7*8=56м²

Answer 2

1) 24:6=4(м 2)- маляр покрасит за 1 час.
2)18:6=3(м 2) - покрасит  ученик за 1 час.
3) (4+3)•8=56(м 2)-они покрасят работая вместе.

Answer 3

Calculation of Painting Area

To calculate the total painting area that the painter and his apprentice can cover in 8 hours of work, we need to determine their combined painting rate per hour.

According to the given information, the painter can cover 24 m² of wall in 6 hours, while his apprentice can cover 18 m² of wall in the same time.

To find their individual painting rates per hour, we can divide the area covered by each person by the number of hours they work:

- The painter's painting rate per hour: 24 m² / 6 hours = 4 m²/hour - The apprentice's painting rate per hour: 18 m² / 6 hours = 3 m²/hour

Now, we can calculate their combined painting rate per hour by adding their individual rates:

- Combined painting rate per hour: 4 m²/hour + 3 m²/hour = 7 m²/hour

Calculation of Total Painting Area

To find the total painting area they can cover in 8 hours of work, we can multiply their combined painting rate per hour by the number of hours they work together:

- Total painting area in 8 hours: 7 m²/hour × 8 hours = 56 m²

Therefore, the painter and his apprentice can paint a total area of 56 m² in 8 hours of work.
