Question

Маляры покрасили 2|5 площади забора. Какова площадь забора, если им осталось покрасить 48 м-2

Answer 1

Вся площадь: 5/5 = 1, Покрасили 2/5 = > осталось 3/5
3/5 = 48
1 = х
Следовательно, х =  48 * 5 /3 = 16*5 = 80

Answer 2

Calculating the Area of the Fence

To calculate the area of the fence, we can use the information provided. The painters have already painted 2/5 of the fence, and there are 48 m² left to paint.

Step 1: Calculate the area already painted: - Let's assume the total area of the fence is represented by F. - The area already painted is 2/5 of the total area, which can be represented as (2/5) * F.

Step 2: Calculate the remaining area to be painted: - The remaining area to be painted is 48 m².

Step 3: Calculate the total area of the fence: - We can use the information from the steps above to find the total area of the fence.

Calculation

- Let's represent the total area of the fence as F. - The area already painted is 2/5 of the total area, which can be represented as (2/5) * F. - The remaining area to be painted is 48 m². - We can set up the equation: (2/5) * F + 48 = F.

Solution

- Solving the equation (2/5) * F + 48 = F for F, we get: - (2/5) * F + 48 = F - 48 = F - (2/5) * F - 48 = (3/5) * F - F = 48 / (3/5) - F = 48 * (5/3) - F = 80

The total area of the fence is 80 square meters.
