Question

два маляра покрасили вместе 144 рамы.один из них работал 6 дней по 7 часов в день а другой 5 дней по 6 часов в день сколько рам покрасил каждый маляр если за 1 час работы они красили одинаковое количество рам

Answer 1

1) 6 * 7 = 42 (ч) - столько часов проработал первый маляр;
2) 5 * 6 = 30 (ч) - столько часов проработал второй маляр;
3) 42 + 30 = 72 (ч) - столько времени они проработали вместе;
4) 144 : 72 = 2 (рамы) - за 1 час работы;
5) 42 * 2 = 84 (рамы) - покрасил первый маляр;
6) 30 * 2 = 60 (рам) - покрасил второй маляр.
Ответ: 84 рамы покрасил первый маляр и 60 рам покрасил второй маляр.  

Answer 2

Problem Analysis

We are given that two painters worked together to paint 144 frames. One painter worked for 6 days, 7 hours per day, while the other painter worked for 5 days, 6 hours per day. We need to determine how many frames each painter painted if they painted an equal number of frames per hour of work.

Solution

Let's calculate the total number of hours worked by each painter and then divide the total number of frames by the total number of hours to find the number of frames painted per hour. Since both painters painted an equal number of frames per hour, we can use this information to find the number of frames painted by each painter.

Painter 1: - Worked for 6 days, 7 hours per day. - Total hours worked = 6 * 7 = 42 hours.

Painter 2: - Worked for 5 days, 6 hours per day. - Total hours worked = 5 * 6 = 30 hours.

Total frames painted = 144 frames.

Let's calculate the number of frames painted per hour by dividing the total frames by the total hours worked: - Frames painted per hour = Total frames / Total hours - Frames painted per hour = 144 frames / (42 hours + 30 hours)

Now, we can calculate the number of frames painted by each painter by multiplying the frames painted per hour by the number of hours worked by each painter.

Painter 1: - Frames painted by Painter 1 = Frames painted per hour * Total hours worked by Painter 1 - Frames painted by Painter 1 = Frames painted per hour * 42 hours

Painter 2: - Frames painted by Painter 2 = Frames painted per hour * Total hours worked by Painter 2 - Frames painted by Painter 2 = Frames painted per hour * 30 hours

Let's calculate the frames painted per hour and the number of frames painted by each painter.

Calculation

Total hours worked = 42 hours + 30 hours = 72 hours

Frames painted per hour = 144 frames / 72 hours = 2 frames per hour

Painter 1: - Frames painted by Painter 1 = 2 frames per hour * 42 hours = 84 frames

Painter 2: - Frames painted by Painter 2 = 2 frames per hour * 30 hours = 60 frames

Answer

Each painter painted a different number of frames: - Painter 1 painted 84 frames. - Painter 2 painted 60 frames.
