Question

В первый день истратили 4//9 ящика гвоздей.а во второй день на 1//12 ящика меньше.чем в первый.Какую часть ящика гвоздей истратили за эти два дня.

Answer 1

Решение:
Если в первый день истратили 4/9 ящика гвоздей, то во второй день согласно условию задачи истратили:
4/9-1/12=4*4/36-1*3/36=16/36-3/36=13/36(ящика гвоздей)
Всего за дня истратили гвоздей:
4/9+13/36=4*4/36+13/36=16/36+13/36=29/36 (ящика гвоздей)

Ответ: 29/36

Answer 2

Calculating the Fraction of Nails Used

To calculate the fraction of the nail box used over the two days, we can follow these steps:

1. Calculate the Total Nails Used on the First Day: - On the first day, 4/9 of a nail box was used.

2. Calculate the Total Nails Used on the Second Day: - On the second day, the number of nails used was 1/12 less than the first day.

3. Find the Total Nails Used over Two Days: - Add the nails used on the first and second days to find the total nails used.

4. Calculate the Fraction of the Nail Box Used: - Divide the total nails used by the total nails in a box to find the fraction used.

Let's calculate the fraction of the nail box used over the two days.

Calculation

1. Total Nails Used on the First Day: - 4/9 of the nail box was used on the first day.

2. Total Nails Used on the Second Day: - The nails used on the second day were 1/12 less than the first day.

3. Total Nails Used over Two Days: - Add the nails used on the first and second days.

Calculation: (4/9) + (4/9 - 1/12)

- (4/9) + (4/9 - 1/12) = (4/9) + (16/36 - 3/36) = (4/9) + (13/36) = (16/36) + (13/36) = 29/36

4. Fraction of the Nail Box Used: - The fraction of the nail box used over the two days is 29/36.

So, 29/36 of the nail box was used over the two days.
