Question

На 24 м забора израсходовали 9 кг краски. Сколько краски израсходуют на 28 м этого забора?

Answer 1

10,5кг краски на 28 м

Answer 2

Calculating Paint Usage for the Fence

To calculate the amount of paint needed for a 28m fence based on the usage for a 24m fence, we can use a simple proportion.

Given: - Length of the first fence (L1) = 24m - Amount of paint used for the first fence (P1) = 9kg - Length of the second fence (L2) = 28m

We can set up the proportion as follows: L1 : L2 = P1 : P2

Calculating the Amount of Paint for the 28m Fence

Using the proportion, we can calculate the amount of paint (P2) needed for the 28m fence: P2 = (P1 * L2) / L1

Substituting the given values: P2 = (9kg * 28m) / 24m

Result

P2 = 10.5kg

So, the amount of paint needed for the 28m fence would be 10.5kg.
