Question

Два тракториста вспахали 12,32 га земли ,причём один из них вспахал в 1,2 раза меньше другого .Сколько гектаров земли вспахал каждый тракторист?

Answer 1

Пусть один вспахал х га земли, тогда второй - 1,2х га. Зная, что вместе они вспахали 12,32 га земли, составляем уравнение:
х+1,2х=12,32
2,2х=12,32
х=12,32:2,2
х=5,6 га вспахал один тракторист
1,2 х 5,6=6,72 (га) - вспахал второй тракторист
Ответ. 5,6 га и 6,72 га.

Answer 2

Problem Analysis

Two tractor drivers plowed a piece of land measuring 12.32 hectares. One of them plowed 1.2 times less than the other. We need to determine how many hectares each tractor driver plowed.

Solution

Let's assume that the first tractor driver plowed x hectares of land. Since the second tractor driver plowed 1.2 times less, the second tractor driver plowed 1.2x hectares of land.

According to the problem, the sum of the areas plowed by both tractor drivers is 12.32 hectares. Therefore, we can write the following equation:

x + 1.2x = 12.32

Simplifying the equation:

2.2x = 12.32

Dividing both sides of the equation by 2.2:

x = 12.32 / 2.2

Evaluating the expression:

x ≈ 5.6

Therefore, the first tractor driver plowed approximately 5.6 hectares of land, and the second tractor driver plowed approximately 1.2 times less, which is approximately 4.67 hectares.

Answer

The first tractor driver plowed approximately 5.6 hectares of land, while the second tractor driver plowed approximately 4.67 hectares of land.
