Question

Какую часть стены маляр красит за 1 час, если всю стену он покрасит за 3 3/5 часа?

Answer 1

Можно составить пропорцию.
Вся стена = 1
3 целых и 3/5 часа это 3,6 часа

1/3,6ч = х/1ч
Итого х = 0,36 стены
Это принцип. Расписывай, как считаешь нужным.

Answer 2

Примем всю стену за 1
1:3 3/5=1:18/5=5/18 часть
Ответ: за 1 час маляр покрасит 5/18 стены

Answer 3

Calculating the Rate of Painting

To calculate the rate at which the painter is able to paint a wall, we can use the information provided.

Let's denote: - x as the fraction of the wall the painter can paint in 1 hour. - 3 3/5 hours as the total time it takes for the painter to paint the entire wall.

We can set up the equation: x * 3 3/5 = 1

Solving for x

To solve for x, we can first convert 3 3/5 hours to an improper fraction: 3 3/5 = (5 * 3 + 3) / 5 = 18/5

Now, we can solve for x: x * 18/5 = 1

To find x, we can multiply both sides by the reciprocal of 18/5, which is 5/18: x = 1 * 5/18 = 5/18

So, the painter can paint 5/18 of the wall in 1 hour.

Conclusion

Therefore, the painter can paint 5/18 of the wall in 1 hour.
