Calculation of Firewood Collected by Petr Ivanovich

To calculate the fraction of firewood collected by Petr Ivanovich in one day, we need to use the information provided. According to the question, Petr Ivanovich collected 4/7 of the necessary amount of firewood for the winter in 12 days.

Let's break down the information given:

- Petr Ivanovich collected 4/7 of the necessary amount of firewood. - He collected this amount in 12 days.

To find out how much firewood Petr Ivanovich collects in one day, we can divide the total amount collected by the number of days it took him.

Let's perform the calculation:

Amount of firewood collected in one day = (Amount of firewood collected) / (Number of days)

Amount of firewood collected in one day = (4/7) / 12

To simplify the calculation, we can convert the fraction 4/7 into a decimal:

Amount of firewood collected in one day = (4/7) / 12 = 0.19047619047619047

Therefore, Petr Ivanovich collects approximately 0.1905 (rounded to four decimal places) or 19.05% of the necessary amount of firewood in one day.

Please note that the calculation is based on the information provided in the question.
