Question

С 2 га поля собрали 700 ц сахарной свеклы.Сколько тонн сахарной свеклы собрали с 7 га?С поля какой площади собрали 280 тонн сахарной свеклы?

Answer 1

700:2=350 ц с 1 га
350×7=2450 ц - с 7 га
280 т=2800 ц
2800:350=8 га

Answer 2

1)  а) 700 : 2 = 350 (ц)- собрали с 1 га

     б)350 х 7 = 2450 (ц) = 245 (т) - собрали с 7 га

 

2) 1 т = 10 ц

     а)280 х 10 = 2800 (ц)

     б)2800 : 350 = 8 (га)

 

Ответ: 245 т свеклы собрали с 7 га и 280 т свеклы собрали с 8 га.

Answer 3

Calculation 1: Сколько тонн сахарной свеклы собрали с 7 га?

To calculate the amount of sugar beets harvested from 7 hectares (га) based on the information provided, we can use the given data from 2 hectares (га) and apply it proportionally.

Given: - 2 hectares (га) produced 700 tons (ц) of sugar beets.

To find the amount of sugar beets harvested from 7 hectares (га), we can set up a proportion:

2 hectares (га) is to 700 tons (ц) as 7 hectares (га) is to X tons (ц).

Using the proportion, we can solve for X:

2/700 = 7/X

Cross-multiplying, we get:

2X = 700 * 7

Simplifying, we find:

2X = 4900

Dividing both sides by 2, we get:

X = 2450

Therefore, the amount of sugar beets harvested from 7 hectares (га) is 2450 tons (ц).

Calculation 2: С поля какой площади собрали 280 тонн сахарной свеклы?

To calculate the area of the field from which 280 tons (тонн) of sugar beets were harvested, we can use the given data from 2 hectares (га) and apply it proportionally.

Given: - 2 hectares (га) produced 700 tons (ц) of sugar beets.

To find the area of the field that produced 280 tons (тонн) of sugar beets, we can set up a proportion:

2 hectares (га) is to 700 tons (ц) as X hectares (га) is to 280 tons (ц).

Using the proportion, we can solve for X:

2/700 = X/280

Cross-multiplying, we get:

2 * 280 = 700 * X

Simplifying, we find:

560 = 700X

Dividing both sides by 700, we get:

X = 560/700

Simplifying further, we find:

X = 0.8

Therefore, the area of the field from which 280 tons (тонн) of sugar beets were harvested is 0.8 hectares (га).
