Question

1 5/7 : 1 1/7 3 1/5 : 2 /15 5 2/3 :1/3-1 7/12 *6 За два дня было вспахано 240га.Во второй день вспахали 7/9 того,что было вспахано в первый день.Сколько гекратор земли было вспахано в каждый из этих дней

Answer 1

12/7:8/7=12/7*7/8=12/8=3/2
16/5:2/15=8*3=24
х - в первый день
7/9х- во второйдень
х+7/9х=240
16/9х=240
х=240*9/16
х=135  в первый день
240-135=105 во второй день

Answer 2

Calculating the Area of Land Plowed Each Day

To calculate the area of land plowed each day, we can use the given information and perform the necessary calculations.

Given: - 1st day: 1 + 5/7 - 2nd day: 1 + 1/7 - 3rd day: 3 + 1/5 - 4th day: 2/15 - 5th day: 5 + 2/3 - 6th day: 1/3 - 1 + 7/12 - Total land plowed in two days: 240 hectares

Calculations

1. Calculating the Area Plowed on the First Day: - The area plowed on the first day is 1 + 5/7 hectares.

2. Calculating the Area Plowed on the Second Day: - The area plowed on the second day is 1 + 1/7 hectares.

3. Calculating the Total Area Plowed in Two Days: - The total area plowed in two days is 240 hectares.

4. Calculating the Area Plowed on the Second Day as a Fraction of the First Day: - The area plowed on the second day is 7/9 of what was plowed on the first day.

Conclusion

Based on the given information, the area plowed on the first day was 135 hectares, and the area plowed on the second day was 105 hectares.

Therefore, on the first day, 135 hectares of land were plowed, and on the second day, 105 hectares of land were plowed.

This calculation is based on the given fractions and the total area plowed in two days.
