Question

3. Реши задачи. 1) До станции поезд должен пройти 98 км. Он прошёл седьмую часть пути. Сколько километров прошёл поезд?2) После того как лесник посадил 13 рядов саженцев дуба по 7 деревьев в каждом, ему осталось посадить ещё 200 саженцев. Сколько всего саженцев должен был посадить лесник?3) Туристы прошли 12 км. Это составило шестую часть всего пути. Сколько километров они должны пройти?

Answer 1

Ответ:

                                1)

1) 98:7=14 (км).

Ответ: 14 километров прошёл поезд.

                                 2)

7*13+200=291 (с.)

Ответ: 291 саженец должен был посадить лесник.

                                 3)

1) 12*6=72 (км.)

Ответ: 72 километра туристы должны пройти.

Answer 2

Ответ:

1)14км

Пошаговое объяснение:

98:7=14км

2) 291 всего

Пошаговое объяснение:

13×7=91 200+91=291 саженцев

3)12 км х 6 = 72 км длина всего маршрута

Answer 3

Problem 1: Distance traveled by a train

To solve this problem, we need to find the distance traveled by the train given that it has covered one-seventh of the total distance, which is 98 km.

Let's calculate the distance traveled by the train: - Total distance: 98 km - Fraction of the total distance covered: one-seventh (1/7)

To find the distance traveled by the train, we can multiply the total distance by the fraction covered: Distance traveled by the train = Total distance * Fraction covered

Substituting the values: Distance traveled by the train = 98 km * (1/7)

Calculating the result: Distance traveled by the train = 14 km

Therefore, the train has traveled 14 km.

Problem 2: Total number of tree saplings to be planted

In this problem, we need to determine the total number of tree saplings the forester should have planted, given that they have already planted 13 rows of oak saplings with 7 trees in each row, and they still need to plant 200 saplings.

Let's calculate the total number of saplings the forester should have planted: - Number of rows planted: 13 - Number of trees in each row: 7 - Number of remaining saplings to be planted: 200

To find the total number of saplings, we can multiply the number of rows planted by the number of trees in each row and add the number of remaining saplings: Total number of saplings = (Number of rows planted * Number of trees in each row) + Number of remaining saplings

Substituting the values: Total number of saplings = (13 * 7) + 200

Calculating the result: Total number of saplings = 91 + 200

Total number of saplings = 291

Therefore, the forester should have planted 291 saplings in total.

Problem 3: Total distance to be traveled by tourists

In this problem, we need to determine the total distance the tourists should travel, given that they have already traveled 12 km, which is one-sixth of the total distance.

Let's calculate the total distance the tourists should travel: - Distance already traveled: 12 km - Fraction of the total distance traveled: one-sixth (1/6)

To find the total distance, we can divide the distance already traveled by the fraction traveled: Total distance = Distance already traveled / Fraction traveled

Substituting the values: Total distance = 12 km / (1/6)

Calculating the result: Total distance = 12 km * 6

Total distance = 72 km

Therefore, the tourists should travel a total distance of 72 km.
