Question

За первый месяц Ильдар исписал 3|8 всех фломастеров, а за следующий месяц - 2|5 остатка. Сколько фломастеров у него осталось через два месяца? На сколько месяцев хватит оставшихся фломастеров, если каждый месяц использовать по 3 фломастера?

Answer 1

Сколько фломастеров было,а?

Answer 2

Calculation of Remaining Markers

To calculate the number of markers Ildar has left after two months, we need to consider the number of markers he used in the first month and the number of markers he used in the second month.

In the first month, Ildar used 3/8 of all the markers he had. In the second month, he used 2/5 of the remaining markers.

Let's calculate the number of markers Ildar has left after two months.

1. First Month: - Ildar used 3/8 of all the markers he had. - This means he has 5/8 of the markers left.

2. Second Month: - Ildar used 2/5 of the remaining markers from the first month. - Multiplying 5/8 by 2/5, we get: (5/8) * (2/5) = 10/40 = 1/4. - This means Ildar has 1/4 of the markers left after the second month.

Therefore, Ildar has 1/4 of the markers left after two months.

Calculation of Remaining Months

To calculate how many months the remaining markers will last, we need to divide the number of remaining markers by the number of markers used per month.

Ildar uses 3 markers per month.

Let's calculate how many months the remaining markers will last.

1. Remaining Markers: - Ildar has 1/4 of the markers left. - Multiplying 1/4 by the total number of markers, we get: (1/4) * Total Markers.

2. Calculation of Months: - To calculate the number of months, we need to divide the remaining markers by the markers used per month. - Dividing (1/4) * Total Markers by 3, we get: ((1/4) * Total Markers) / 3.

Therefore, the remaining markers will last for ((1/4) * Total Markers) / 3 months.

Please note that the total number of markers is not provided in the question, so we cannot provide an exact number of months. However, you can substitute the value of the total markers into the equation to calculate the result.
