0.5 или же 1/2

Пошаговое объяснение:

кило за 8 минут, а 4 минуты это половина от 8, следовательно и картошки в 2 раза меньше

Answer 2

Calculation of Potato Peeling Rate

To calculate how many kilograms of potatoes a cook can peel in 4 minutes, given that they can peel 1 kilogram in 8 minutes, we can use the concept of proportions.

Let's assume that the amount of potatoes peeled is directly proportional to the time taken. This means that if the cook can peel 1 kilogram of potatoes in 8 minutes, they can peel x kilograms in 4 minutes.

Using the concept of proportions, we can set up the following equation:

1 kilogram / 8 minutes = x kilograms / 4 minutes

To solve for x, we can cross-multiply and then divide:

1 kilogram * 4 minutes = 8 minutes * x kilograms

4 kilograms = 8 minutes * x kilograms

Dividing both sides of the equation by 8 minutes:

4 kilograms / 8 minutes = x kilograms

Simplifying the equation:

0.5 kilograms = x kilograms

Therefore, the cook can peel 0.5 kilograms of potatoes in 4 minutes.

Writing the Answer in Fractions

To write the answer in fractions, we can express the result as a fraction of the total amount of potatoes peeled in 8 minutes.

Since the cook can peel 1 kilogram of potatoes in 8 minutes, we can represent this as 1/8 kilograms per minute.

To find out how many kilograms the cook can peel in 4 minutes, we can multiply the rate per minute by the number of minutes:

1/8 kilograms per minute * 4 minutes = 4/8 kilograms

Simplifying the fraction:

4/8 kilograms = 1/2 kilograms

Therefore, the cook can peel 1/2 kilogram of potatoes in 4 minutes.
