Question

Для животного уголка сделали 3 одинаковые большие клетки и 5 маленьких. На каждую маленькую клетку пошло 8 м проволки. Сколько метров проволки понадобилось на изготовление 1 большой клетки, если на все клетки израсходовали 76 м проволки Реши задачу по действиям с пояснением.

Answer 1

5х8 =40 метров на маленькие клетки.
76-40=36 м вся проволока на большие
36:3 =12 м на одну большую

Answer 2

Task Analysis

To solve this problem, we need to determine the amount of wire needed to make one large cell, given that there are 3 large cells and 5 small cells, and a total of 76 meters of wire was used for all the cells.

Solution

To find the amount of wire needed for one large cell, we can follow these steps: 1. Calculate the total amount of wire used for the small cells. 2. Subtract the total amount of wire used for the small cells from the total amount of wire used for all cells to find the amount of wire used for the large cells. 3. Divide the amount of wire used for the large cells by the number of large cells to find the amount of wire needed for one large cell.

Step 1: Calculate the total amount of wire used for the small cells

The total amount of wire used for the small cells can be calculated by multiplying the number of small cells by the amount of wire used for each small cell.

Total amount of wire used for small cells = 5 small cells * 8 meters of wire per small cell

Using the given information: Total amount of wire used for small cells = 5 * 8 = 40 meters

Step 2: Calculate the amount of wire used for the large cells

The amount of wire used for the large cells can be calculated by subtracting the total amount of wire used for the small cells from the total amount of wire used for all cells.

Amount of wire used for large cells = Total amount of wire used for all cells - Total amount of wire used for small cells

Using the given information: Amount of wire used for large cells = 76 meters - 40 meters = 36 meters

Step 3: Find the amount of wire needed for one large cell

To find the amount of wire needed for one large cell, we can divide the amount of wire used for the large cells by the number of large cells.

Amount of wire needed for one large cell = Amount of wire used for large cells / Number of large cells

Using the given information: Amount of wire needed for one large cell = 36 meters / 3 large cells = 12 meters

Answer

Therefore, the amount of wire needed for the construction of 1 large cell is 12 meters.
