Question

Для посева было приготовлено 25,2 т. семян. В первый день на посев израсходовали 4/9 всех семян, а во второй - 4/7 остатка. Сколько семян осталось после двух дней посева?

Answer 1

25,2 х 4/9 = 11,2 израсходовали в первый день.
25,2-11,2=14 осталось после одного дня
14 х 4/7 = 8 израсходовали во второй день
14-8=6 осталось после двух дней посева

Answer 2

Calculation of Remaining Seeds after Two Days of Sowing

To calculate the remaining seeds after two days of sowing, we can follow these steps:

1. Calculate the seeds sown on the first day: - 4/9 of the total seeds were sown on the first day.

2. Calculate the seeds sown on the second day: - On the second day, 4/7 of the remaining seeds after the first day were sown.

3. Determine the remaining seeds after two days of sowing: - Subtract the total seeds sown over two days from the initial amount of seeds.

Let's proceed with the calculations.

Calculation Steps

1. Seeds sown on the first day: - Total seeds sown on the first day = (4/9) * 25.2 tons - Total seeds sown on the first day = (4/9) * 25.2 = 11.2 tons.

2. Seeds sown on the second day: - Remaining seeds after the first day = 25.2 - 11.2 = 14 tons - Total seeds sown on the second day = (4/7) * 14 tons - Total seeds sown on the second day = (4/7) * 14 = 8 tons.

3. Remaining seeds after two days of sowing: - Remaining seeds after two days = 25.2 - 11.2 - 8 = 6 tons

Answer

After two days of sowing, 6 tons of seeds are remaining.
